PASS theory of intelligence

Last updated

The Planning, Attention-Arousal, Simultaneous and Successive (P.A.S.S.) theory of intelligence, first proposed in 1975 by Das, Kirby and Jarman (1975), [1] and later elaborated by Das, Naglieri & Kirby (1994) [2] and Das, Kar & Parrilla (1996), [3] challenges g-theory, on the grounds that the brain is made up of interdependent but separate functional systems. Neuroimaging studies and clinical studies of individuals with brain lesions make it clear that the brain is modularized; for example, damage to a particular area of the left temporal lobe will impair spoken and written language's production (but not comprehension). Damage to an adjacent area will have the opposite impact, preserving the individual's ability to produce but not understand speech and text.

The P.A.S.S. (Planning, Attention, Simultaneous and Successive cognitive processing) theory of intelligence identifies three operational units that are important to understand mental functioning: attention, simultaneous and successive processing, and planning. The PASS theory of intelligence is based on the psychological work of A.R.Luria. The P.A.S.S. model is an alternative approach to measuring and studying intelligence. [4]

Description

The PASS Theory of Intelligence [2] posits that cognition is organized in three systems and four processes, based on A. R. Luria's (1966) work on modularization of brain activity and validated by decades of neuroimaging data. The first phase is planning, which entails executive functions directing and organizing behavior, selecting and developing strategies, and monitoring performance. The second is the Attention process, responsible for sustaining arousal and alertness and focusing on relevant inputs. Simultaneous and Successive Processing are procedures that encode, transform, and retain data. Simultaneous processing determines the relationship between objects, and integration into entire information units is necessary. Examples include recognizing figures, such as a triangle within a circle vs. a circle within a triangle. Successive processing is required for organizing separate items in a sequence, such as remembering a sequence of words or actions precisely in the order in which they had just been presented. These four processes are hypothesized to function in four areas of the brain. Planning is broadly located in the front part of our brains, the frontal lobe. Attention and arousal are combined functions of the frontal lobe and the lower parts of the cortex, although the parietal lobes are also involved in attention. Simultaneous processing and Successive processing occur in the posterior region or the back of the brain. Concurrent processing is broadly associated with the occipital and the parietal lobes, while Successive processing is broadly associated with the frontal-temporal lobes.The PASS (Planning/Attention/Simultaneous/Successive) theory is heavily indebted to both Luria (1966, 1973), and studies in cognitive psychology involved in promoting a different look at intelligence. [5]

Assessment of PASS processes

The PASS Theory of Intelligence.jpg

The PASS theory provides the theoretical framework for a measurement instrument called the Das-Naglieri Cognitive Assessment System (CAS), published in 1997. [6] This test, now in a Second Edition (CAS2; 2014, Naglieri, Das & Gold-stein) is designed to provide an assessment of intellectual functioning redefined as four brain-based cognitive processes (Planning, Attention, Simultaneous and Successive), providing information about cognitive strengths and weaknesses of each of the four processes. This emphasis on processes (rather than traditional abilities) is said to make it useful for differential diagnosis; diagnosing learning disabilities and Attention Deficit Disorder, Autism, Intellectual disabilities, cognitive changes in aging and Down syndrome, changes due to brain impairment in stroke and fair and equitable assessment of diverse populations. Its usefulness as a theory and measurement instrument for Planning and Decision making in management has also been demonstrated. [3]

Contemporary theories about intelligence can be divided into two classes: psychometric and cognitive. The quantitative approach to intelligence is better reflected in psychometric theories of which Charles Spearman's is an early example. In contrast, cognitive theories such as PASS theory are both qualitative and quantitative. Such theories advance the idea that intelligence has multiple cognitive processes. For example, both Robert Sternberg and Howard Gardner view intelligence as neither a single nor a biologically determined factor, but as a number of domains that represent the interaction of the individual's biological predispositions with the environment and cultural context. The PASS theory builds upon these principles. [2] In a study by Keith et al. (2001), the g-factor derived via factor-analysis from the Woodcock–Johnson III, a standard IQ-test, correlated almost perfectly (r = 0.98) with the g-factor derived from the CAS. [7]

The core idea that cognitive functions can be organized in terms of broad functions of the brain received some support in a recent study (Okuhata et al.) that investigated the psychophysiology basis of two different types of information processing (simultaneous and successive). The authors investigated EEG coherence patterns during six tasks of the Das-Naglieri Cognitive Assessment System. [6] They analyzed beta (12.5 – 25. Hz) coherence while 18 volunteers performed three simultaneous and three successive tasks. The results revealed two significantly distinguishable coherence patterns corresponding to simultaneous and successive processing. The linking of PASS processes to the brain becomes helpful. For example, in the understanding the loss of sequential and planning functions due to aging in a study of individuals with Down syndrome, using single positron emission topography, Das [8] found that aging individuals with Down syndrome show a bilateral decreased cerebral blood flow in the temporal-parietal region of the brain. The significance of cognitive profiling studies both in impaired and intact brains awaits further discussion in the broader context of the biology of intelligence.

Remediation and cognitive enhancement

One unusual property of the P.A.S.S. theory of cognitive processes is that it has been proven useful for both intellectual assessment (e.g. the CAS) and educational intervention. The theory provides the theoretical framework for the PASS Reading Enhancement Program, a remediation curriculum designed to improve the planning, attention and information processing strategies that underlie reading. A related school-readiness program aims at improving the foundations of cognitive processes in preparation for schooling (Das, 2009). Both are evidence-based intervention programs. [9]

Challenges

A frequently asked question from the critics of PASS is: are Attention and Planning two distinct factors? Kranzler, Keith & Flanagan (2000) [10] found only a marginal fit for the four-factor model; the attention and planning factors were indistinguishable. Recent research on intelligence tests confirms that the most valid score on, for example, the Wechsler Intelligence Scale for Children – Fifth Edition (Canivez, Watkins, & Dombrowski, 2017), Stanford-Binet Fifth Edition (Canivez, 2008), Differential Abilities Scales (Canivez & McGill, 2016), and the Woodcock-Johnson Fourth Edition (Dombrowski, McGill & Canivez, 2017) is the total score that estimates g. That is, the scores which represent the factor based scales these tests provide do not have enough specific variance to be considered interpretable. In fact, a recent reanalysis of Carroll's survey of factor-analytic studies by Benson, Beaujean, McGill, and Dombrowski (2018) concluded that nearly all of the specified abilities presented by Carroll "have little-to-no interpretive relevance above and beyond that of general intelligence (p. 1028)." The only exception to these finding is research reported by Canivez (2011) regarding the Cognitive Assessment System (Naglieri & Das, 1997).

The most recent factor analytic examination of the PASS scales of the CAS Second Edition was conducted by Papadopoulos, Spanoudis and Naglieri (2023) using the standardization sample of the CAS2. The correlated four-factor solution best fits the data above and beyond the one-factor, second-order, bi-factor, and several asymmetrical bi-factor models. These different models, parameterized to allow for indications of the four cognitive factors (i.e., correlated model), a general g factor (i.e., one- and second-order factor models), or a combination of the two (i.e., bi-factors models), revealed that the correlated model accounted for the inter-subtest covariation of the cognitive abilities better than the unitary g factor or the bifactor models. Furthermore, factorial invariance analysis provided evidence that the obtained correlated model, as an index of cognitive processing or intelligence, was the same between genders.

Psychology is the scientific study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Biological psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.

Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness. Using their intelligence, humans are able to learn, form concepts, understand, and apply logic and reason. Human intelligence is also thought to encompass their capacities to recognize patterns, plan, innovate, solve problems, make decisions, retain information, and use language to communicate.

The g factor is a construct developed in psychometric investigations of cognitive abilities and human intelligence. It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the fact that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks. The g factor typically accounts for 40 to 50 percent of the between-individual performance differences on a given cognitive test, and composite scores based on many tests are frequently regarded as estimates of individuals' standing on the g factor. The terms IQ, general intelligence, general cognitive ability, general mental ability, and simply intelligence are often used interchangeably to refer to this common core shared by cognitive tests. However, the g factor itself is a mathematical construct indicating the level of observed correlation between cognitive tasks. The measured value of this construct depends on the cognitive tasks that are used, and little is known about the underlying causes of the observed correlations.

Neuropsychological tests are specifically designed tasks that are used to measure a psychological function known to be linked to a particular brain structure or pathway. Tests are used for research into brain function and in a clinical setting for the diagnosis of deficits. They usually involve the systematic administration of clearly defined procedures in a formal environment. Neuropsychological tests are typically administered to a single person working with an examiner in a quiet office environment, free from distractions. As such, it can be argued that neuropsychological tests at times offer an estimate of a person's peak level of cognitive performance. Neuropsychological tests are a core component of the process of conducting neuropsychological assessment, along with personal, interpersonal and contextual factors.

Traffic psychology is a discipline of psychology that studies the relationship between psychological processes and the behavior of road users.

The latest version, WPPSI–IV, published by Pearson Education, is a revision of the WPPSI-R and the WPPSI-III. It provides subtest and composite scores that represent intellectual functioning in verbal and performance cognitive domains, as well as providing a composite score that represents a child's general intellectual ability.

The Kaufman Assessment Battery for Children (KABC) is a clinical instrument for assessing cognitive development. Its construction incorporates several recent developments in both psychological theory and statistical methodology. The test was developed by Alan S. Kaufman and Nadeen L.

The test has been translated and adopted for many countries, such as the Japanese version of the K-ABC by the Japanese psychologists Tatsuya Matsubara, Kazuhiro Fujita, Hisao Maekawa, and Toshinori Ishikuma.

The Culture Fair Intelligence Test (CFIT) was created by Raymond Cattell in 1949 as an attempt to measure cognitive abilities devoid of sociocultural and environmental influences. Scholars have subsequently concluded that the attempt to construct measures of cognitive abilities devoid of the influences of experiential and cultural conditioning is a challenging one. Cattell proposed that general intelligence (g) comprises both fluid intelligence (Gf) and crystallized intelligence (Gc). Whereas Gf is biologically and constitutionally based, Gc is the actual level of a person's cognitive functioning, based on the augmentation of Gf through sociocultural and experiential learning.

Cognitive impairment is an inclusive term to describe any characteristic that acts as a barrier to the cognition process or different areas of cognition. Cognition, also known as cognitive function, refers to the mental processes of how a person gains knowledge, uses existing knowledge, and understands things that are happening around them using their thoughts and senses. A cognitive impairment can be in different domains or aspects of a person's cognitive function including memory, attention span, planning, reasoning, decision-making, language, executive functioning, and visuospatial functioning. The term cognitive impairment covers many different diseases and conditions and may also be symptom or manifestation of a different underlying condition. Examples include impairments in overall intelligence, specific and restricted impairments in cognitive abilities, neuropsychological impairments, or it may describe drug-induced impairment in cognition and memory. Cognitive impairments may be short-term, progressive or permanent.

The Das–Naglieri cognitive assessment system (CAS) test is an individually administered test of cognitive functioning for children and adolescents ranging from 5 through 17 years of age that was designed to assess the planning, attention, simultaneous and successive cognitive processes as described in the PASS theory of intelligence.

Neurodevelopmental framework for learning, like all frameworks, is an organizing structure through which learners and learning can be understood. Intelligence theories and neuropsychology inform many of them. The framework described below is a neurodevelopmental framework for learning. The neurodevelopmental framework was developed by the All Kinds of Minds Institute in collaboration with Dr. Mel Levine and the University of North Carolina's Clinical Center for the Study of Development and Learning. It is similar to other neuropsychological frameworks, including Alexander Luria's cultural-historical psychology and psychological activity theory, but also draws from disciplines such as speech-language pathology, occupational therapy, and physical therapy. It also shares components with other frameworks, some of which are listed below. However, it does not include a general intelligence factor, since the framework is used to describe learners in terms of profiles of strengths and weaknesses, as opposed to using labels, diagnoses, or broad ability levels. This framework was also developed to link with academic skills, such as reading and writing. Implications for education are discussed below as well as the connections to and compatibilities with several major educational policy issues.

Nelson Cowan is the Curators' Distinguished Professor of Psychological Sciences at the University of Missouri. He specializes in working memory, the small amount of information held in mind and used for language processing and various kinds of problem solving. To overcome conceptual difficulties that arise for models of information processing in which different functions occur in separate boxes, Cowan proposed a more organically organized "embedded processes" model. Within it, representations held in working memory comprise an activated subset of the representations held in long-term memory, with a smaller subset held in a more integrated form in the current focus of attention. Other work has been on the developmental growth of working memory capacity and the scientific method. His work, funded by the National Institutes of Health since 1984, has been cited over 41,000 times according to Google Scholar. The work has resulted in over 250 peer-reviewed articles, over 60 book chapters, 2 sole-authored books, and 4 edited volumes.

The Halstead–Reitan Neuropsychological Test Battery (HRNB) and allied procedures is a comprehensive suite of neuropsychological tests used to assess the condition and functioning of the brain, including etiology, type, localization and lateralization of brain injury. The HRNB was first constructed by Ward C. Halstead, who was chairman of the Psychology Department at the University of Chicago, together with his doctoral student, Ralph Reitan. A major aim of administering the HRNB to patients was if possible to lateralize a lesion to either the left or right cerebral hemisphere by comparing the functioning on both sides of the body on a variety of tests such as the Suppression or Sensory Imperception Test, the Finger Agnosia Test, Finger Tip Writing, the Finger Tapping Test, and the Tactual Performance Test. One difficulty with the HRNB was its excessive administration time. In particular, administration of the Halstead Category Test was lengthy, so subsequent attempts were made to construct reliable and valid short-forms.

In modern psychology, vigilance, also termed sustained concentration, is defined as the ability to maintain concentrated attention over prolonged periods of time. During this time, the person attempts to detect the appearance of a particular target stimulus. The individual watches for a signal stimulus that may occur at an unknown time.
