Larry L. Jacoby (born March 11, 1944) is an American cognitive psychologist specializing in research on human memory. He is particularly known for his work on the interplay of consciously controlled versus more automatic influences of memory.
The Association for Psychological Science (APS) selected Jacoby as a 2013 winner of the William James Fellow Award for members "recognized internationally for their outstanding contributions to scientific psychology". [1] In his profile in the APS journal, Observer, Jacoby is described as "one of the world's foremost researchers on memory". [2] The Society of Experimental Psychologists awarded him the 2013 Norman Anderson Lifetime Achievement Award. Jacoby is on the Thomson Reuters list of highly cited researchers (an explicit definition of scholarly influence). [3] From 1994 to 1995, Jacoby held an endowed position, the David Wechsler Chair at the University of Texas at Austin.
Harzing's Publish or Perish [4] credits Jacoby with an h-index of 69 (86 as of 8.2019) and more than 23,000 citations (36223 as of 8.2019). PsycINFO lists 153 works by Jacoby. Jacoby's work also figures prominently in many undergraduate textbooks. [5] [6] [7] The Oxford Handbook of Memory cites Jacoby's work on 73 different pages. [8] Similarly, multiple citations of Jacoby's work appear in each of the three volumes of The Psychology of Memory. [9] Jacoby has coauthored works with Dave Balota (Wash U), Lee Brooks (deceased; formerly at McMaster), Laird Cermak (deceased, formerly of Boston U), Fergus I. M. Craik (University of Toronto), Robyn Dawes (deceased; formerly at Carnegie-Mellon), John Dunlosky (Kent State), Mark McDaniel (Wash U.), and Daniel Schacter (Harvard). Jacoby's former students include Andrew Yonelinas, Diane St. Marie, Janine Jennings, Janine Hay, Jeffrey Toth, Karen Daniels, Matt Rhodes, and Stephen Lindsay, among others. Jacoby has long maintained a productive collaboration with Colleen M. Kelley.
Jacoby earned his undergraduate degree at Washburn University, and his MA and PhD (in 1970) at Southern Illinois University under the supervision of Robert Radtke. His first academic post was at Iowa State University. He was on the faculty of McMaster University (Hamilton, Ontario, Canada) for many years, where he collaborated with colleagues Lee Brooks, Ian Begg, Betty Ann Levy, and Bruce Milliken and long-time research assistant Ann Hollingshead, and interacted with colleagues at University of Toronto-Erindale including Fergus Craik, Gordon Logan, Morris Moscovitch, and Endel Tulving.
Jacoby spent a year or two at the University of Utah on leave from McMaster. Later, he held the David Wechsler Chair in the Department of Psychology at the University of Texas at Austin. He then moved to New York University for a couple of years, then returned briefly to McMaster, and then moved to Washington University in St. Louis, where Henry L. Roediger III assembled a world-class department of psychology. Jacoby continues to work at Wash U. [10]
Jacoby's work has to do with human memory, and most of it has emphasized episodic memory (that is, the processes and mechanisms that enable us to remember our own past experiences). His early work was in the verbal learning tradition. Jacoby's first publication, in a now-defunct publication of the Psychonomic Society, was McHose, Jacoby, and Meyer 1967. Jacoby published steadily throughout the 1970s, producing a number of works that have attracted multiple citations, such as a 1978 article on how, when a problem is repeated, a person may solve it by remembering the prior solution.
In the 1980s, a major theme in Jacoby's work was that the feeling of remembering does not inhere in the use of memory traces. As he noted, one can use memory records of specific past episodes without having a subjective feeling of remembering (as in involuntary plagiarism) and one can have a subjective feeling of remembering without there being any directly corresponding prior episode and hence no directly corresponding memory trace (as in false-memory phenomena). Jacoby argued that the feeling of remembering arises when a person infers (usually very quickly and without conscious reflection) that current thoughts and images are based on memories of a prior episode – that is, when people attribute current mental events to the past. For a beautifully written and compelling synthesis of Jacoby's work on this perspective, see his 1989 chapter with Colleen Kelley and Jane Dywan in a book in honour of Endel Tulving coedited by Roediger and Craik. In his work with Kelley, he made a distinction between memory that influences performance (he called it "memory as a tool"), which is implicit or unconscious memory outside our awareness, and recollection memory (he called it "memory as an object"), which is conscious memory of an event.
Jacoby is renowned for his methodological creativity and prowess. Jacoby's “logic of opposition” is a particularly lovely methodological innovation. Psychologists have long sought to demonstrate influences of unconscious, automatic processes. A problem is that it is difficult to ensure that responses are not being influenced by conscious processes. [11] [12] For example, a brief prior exposure to a made-up name (e.g., Sebastian Weisdorf) might later lead people taking a test in which they judge names as famous versus nonfamous to mistake that name as famous. That could be an unconscious phenomenon – the subject simply experiences the name as famous and does not recollect the prior encounter with the name. But maybe instead the subject remembers the name from the earlier list and assumes that some or all of the names on that list were of famous people. That is, both unconscious and/or conscious uses of memory for the study-list encounter with “Sebastian Weisdorf” could influence subjects toward endorsing that name as famous. The same problem crops up in a wide range of attempts to demonstrated unconscious influences.
The logic of opposition puts conscious awareness in opposition to being influenced. One way to do this is simply to correctly inform subjects (in the case of this fame procedure) that all of the names on the study list were non-famous. Thus if a subject recollects that a name was on the study list, s/he can confidently identify it as non-famous. Jacoby, Woloshyn, and Kelley (1989) found that when subjects had studied the list with full attention, these opposition instructions led them to be less likely to endorse studied names as famous than to endorse non-studied names as famous. That shows (a) that they sometimes recognized names on the fame test as names on the study list and (b) that they understood that names on the study list were nonfamous. The cool finding was that subjects who studied the list of names under divided attention more often called studied names famous than non-studied names. Presumably dividing attention at study impaired subject ability to consciously recollect which names had been on the list, but left intact more automatic, unconscious influences of familiarity.
The logic of opposition proved a very valuable methodological tool in a variety of different settings. [13] [14] It also formed a key stepping stone in Jacoby's subsequent development of the “process dissociation procedure” (PDP), which Jacoby introduced in a 1991 article in Journal of Memory and Language that became a citation classic. The PDP is a method for obtaining separate quantitative estimates of the concurrent contributions of two different sources of influence on task performance (e.g., conscious vs. unconscious perception; habit vs. intention; familiarity vs. recollection).
For decades cognitive psychologists used individual tasks to measure specific procedures. For example, a recognition memory test might be used to index “explicit” or consciously guided uses of memory whereas a fragment-completion test might be used to index “implicit” or unconscious influences of memory. As Jacoby pointed out, there have been endless problems caused by the fact that tasks are not process-pure. For example, unconscious influences of memory can affect responses on a recognition test, and conscious recollection can affect responses on a fragment completion task. Jacoby presumed that many tasks are influenced by both controlled and automatic processes. To index them, he compared (a) performance when controlled and automatic influences would affect responding in the same direction with (b) performance when controlled influences would oppose the effects of automatic influences. Using simple algebraic equations and certain assumptions, Jacoby derived estimates of the two underlying categories of influence.
The process dissociation procedure was not without its critics (e.g., [15] [16] [17] [18] ), but there is wide agreement that many if not most task performances reflect concurrent automatic and controlled influences and there are good reasons to believe that given appropriate tasks and within certain boundary conditions the assumptions of the PDP hold (e.g., [19] [20] [21] ). Jacoby and former student Andy Yonelinas provided an update on the status of the PDP in a 2012 article.
Jacoby's recent work has explored various aspects of the notion of cognitive control—ways the mind/brain constrains its own operation so as to enhance the production of some kinds of mental contents relative to others. One key notion is that control can often be exercised “at the front end” and thereby modulate the thoughts and images that come to mind (whereas most prior theorizing about control emphasized output monitoring and filtering) (e.g., Halamish, Goldsmith, & Jacoby, 2012; Jacoby, Shimizu, Daniels, & Rhodes, 2005). Another key notion is that the ability to modulate cognitive control develops across childhood and then, late in life, declines, thereby leading to aging-related memory failures (e.g., Jacoby, Rogers, Bishara, & Shimizu, 2012; Jennings & Jacoby, 2003). Jacoby's recent work with postdoc Chris Wahlheim has explored the positive effects of noticing and remembering change on forgetting caused by interference (e.g., Jacoby, Wahlheim, & Kelley, 2015); cf.

Roddy Roediger, Steve Lindsay, Colleen Kelley, and Andy Yonelinas organized a Festschrift in Larry's honour. The event was held at Washington University over two days in the spring of 2013 and featured 24 speakers and an audience of approximately 100 people. The celebration was generously supported by the Wash U. A book featuring 22 chapters based on talks given at this Festschrift was published in 2014 (publication year 2015) by Psychology Press.

Recall in memory refers to the mental process of retrieval of information from the past. Along with encoding and storage, it is one of the three core processes of memory. There are three main types of recall: free recall, cued recall and serial recall. Psychologists test these forms of recall as a way to study the memory processes of humans and animals. Two main theories of the process of recall are the two-stage theory and the theory of encoding specificity.
The testing effect suggests long-term memory is increased when part of the learning period is devoted to retrieving information from memory. It is different from the more general practice effect, defined in the APA Dictionary of Psychology as "any change or improvement that results from practice or repetition of task items or activities."
Endel Tulving was an Estonian-born Canadian experimental psychologist and cognitive neuroscientist. In his research on human memory he proposed the distinction between semantic and episodic memory. Tulving was a professor at the University of Toronto. He joined the Rotman Research Institute at Baycrest Health Sciences in 1992 as the first Anne and Max Tanenbaum Chair in Cognitive Neuroscience and remained there until his retirement in 2010. In 2006, he was named an Officer of the Order of Canada (OC), Canada's highest civilian honour.
The Levels of Processing model, created by Fergus I. M. Craik and Robert S. Lockhart in 1972, describes memory recall of stimuli as a function of the depth of mental processing. Deeper levels of analysis produce more elaborate, longer-lasting, and stronger memory traces than shallow levels of analysis. Depth of processing falls on a shallow to deep continuum. Shallow processing leads to a fragile memory trace that is susceptible to rapid decay. Conversely, deep processing results in a more durable memory trace. There are three levels of processing in this model. Structural processing, or visual, is when we remember only the physical quality of the word E.g how the word is spelled and how letters look. Phonemic processing includes remembering the word by the way it sounds. E.G the word tall rhymes with fall. Lastly, we have semantic processing in which we encode the meaning of the word with another word that is similar of has similar meaning. Once the word is perceived, the brain allows for a deeper processing.
State-dependent memory or state-dependent learning is the phenomenon where people remember more information if their physical or mental state is the same at time of encoding and time of recall. State-dependent memory is heavily researched in regards to its employment both in regards to synthetic states of consciousness as well as organic states of consciousness such as mood. While state-dependent memory may seem rather similar to context-dependent memory, context-dependent memory involves an individual's external environment and conditions while state-dependent memory applies to the individual's internal conditions.
In psychology, memory inhibition is the ability not to remember irrelevant information. The scientific concept of memory inhibition should not be confused with everyday uses of the word "inhibition". Scientifically speaking, memory inhibition is a type of cognitive inhibition, which is the stopping or overriding of a mental process, in whole or in part, with or without intention.
Implicit cognition refers to cognitive processes that occur outside conscious awareness or conscious control. This includes domains such as learning, perception, or memory which may influence a person's behavior without their conscious awareness of those influences.
A source-monitoring error is a type of memory error where the source of a memory is incorrectly attributed to some specific recollected experience. For example, individuals may learn about a current event from a friend, but later report having learned about it on the local news, thus reflecting an incorrect source attribution. This error occurs when normal perceptual and reflective processes are disrupted, either by limited encoding of source information or by disruption to the judgment processes used in source-monitoring. Depression, high stress levels and damage to relevant brain areas are examples of factors that can cause such disruption and hence source-monitoring errors.
Henry L. "Roddy" Roediger III is an American psychology researcher in the area of human learning and memory. He rose to prominence for his work on the psychological aspects of false memories.
Metamemory or Socratic awareness, a type of metacognition, is both the introspective knowledge of one's own memory capabilities and the processes involved in memory self-monitoring. This self-awareness of memory has important implications for how people learn and use memories. When studying, for example, students make judgments of whether they have successfully learned the assigned material and use these decisions, known as "judgments of learning", to allocate study time.
Priming is the idea that exposure to one stimulus may influence a response to a subsequent stimulus, without conscious guidance or intention. The priming effect refers to the positive or negative effect of a rapidly presented stimulus on the processing of a second stimulus that appears shortly after. Generally speaking, the generation of priming effect depends on the existence of some positive or negative relationship between priming and target stimuli. For example, the word nurse might be recognized more quickly following the word doctor than following the word bread. Priming can be perceptual, associative, repetitive, positive, negative, affective, semantic, or conceptual. Priming effects involve word recognition, semantic processing, attention, unconscious processing, and many other issues, and are related to differences in various writing systems. Research, however, has yet to firmly establish the duration of priming effects, yet their onset can be almost instantaneous.
Recognition memory, a subcategory of explicit memory, is the ability to recognize previously encountered events, objects, or people. When the previously experienced event is reexperienced, this environmental content is matched to stored memory representations, eliciting matching signals. As first established by psychology experiments in the 1970s, recognition memory for pictures is quite remarkable: humans can remember thousands of images at high accuracy after seeing each only once and only for a few seconds.
In psychology, implicit memory is one of the two main types of long-term human memory. It is acquired and used unconsciously, and can affect thoughts and behaviours. One of its most common forms is procedural memory, which allows people to perform certain tasks without conscious awareness of these previous experiences; for example, remembering how to tie one's shoes or ride a bicycle without consciously thinking about those activities.
In psychology, the misattribution of memory or source misattribution is the misidentification of the origin of a memory by the person making the memory recall. Misattribution is likely to occur when individuals are unable to monitor and control the influence of their attitudes, toward their judgments, at the time of retrieval. Misattribution is divided into three components: cryptomnesia, false memories, and source confusion. It was originally noted as one of Daniel Schacter's seven sins of memory.
The encoding specificity principle is the general principle that matching the encoding contexts of information at recall assists in the retrieval of episodic memories. It provides a framework for understanding how the conditions present while encoding information relate to memory and recall of that information.
Unconscious cognition is the processing of perception, memory, learning, thought, and language without being aware of it.
Retrieval-induced forgetting (RIF) is a memory phenomenon where remembering causes forgetting of other information in memory. The phenomenon was first demonstrated in 1994, although the concept of RIF has been previously discussed in the context of retrieval inhibition.
The rhyme-as-reason effect, or Eaton–Rosen phenomenon, is a cognitive bias whereupon a saying or aphorism is judged as more accurate or truthful when it is rewritten to rhyme.
The Perruchet effect is a psychological phenomenon in which a dissociation is shown between conscious expectation of an event and the strength or speed of a response to the event. This can be demonstrated by sequential analyses of consecutive trials such as eye blinking conditioning, electrodermal shocks and cued go/no-go task. The dissociation design differentiates the automatic associative strength and propositional expectation's effects on associative learning and conditioning, i.e., the cognitive learning process with relationship between events.
