Cognitive-behavioral therapy and decision science

In recent decades cognitive-behavioral therapy (CBT) and decision science (DS) have emerged within the field of psychological science. Though these are two vastly different areas of study, they are similar in that they address human information processing, cognition, behavior, and the link between them. In this article, we provide brief summaries of CBT and decision science, discuss their similarities and differences, and discuss how future research can identify ways in which these fields can inform each other. Several CBT techniques that might be of use to the efforts of the decision science field to prevent cognitive biases are suggested. Research that integrates these two fields may lead to the improvement of both.     

Exploring the Hierarchical Structure of the MMPI–2–RF Personality Psychopathology Five in Psychiatric Patient and University Student Samples

In this study our goal was to examine the hierarchical structure of personality pathology as conceptualized by Harkness and McNulty's (1994) Personality Psychopathology Five (PSY–5) model, as recently operationalized by the MMPI–2–RF (Ben-Porath & Tellegen, 2011) PSY–5r scales. We used Goldberg's (2006) “bass-ackwards” method to obtain factor structure using PSY–5r item data, successively extracting from 1 to 5 factors in a sample of psychiatric patients (n = 1,000) and a sample of university undergraduate students (n = 1,331). Participants from these samples had completed either the MMPI–2 or the MMPI–2–RF. The results were mostly consistent across the 2 samples, with some differences at the 3-factor level. In the patient sample a factor structure representing 3 broad psychopathology domains (internalizing, externalizing, and psychoticism) emerged; in the student sample the 3-factor level represented what is more commonly observed in “normal-range” personality models (negative emotionality, introversion, and disconstraint). At the 5-factor level the basic structure was similar across the 2 samples and represented well the PSY–5r domains.     

The factor structure of the Anxiety Sensitivity Index among Northern Plains Native Americans

Within our current research climate, an emphasis has been placed on examining the cross-cultural applicability of psychological tools, and exploring their utility with people of different backgrounds. Within this line of investigation lies the risk of classifying people too broadly and masking important regional, tribal, or dialectical differences. This may be particularly potent among Native Americans, given the number of distinct indigenous entities. This study examined the psychometric characteristics of the Anxiety Sensitivity Index with a tribally homogeneous sample, as compared to previous tribally-heterogeneous and majority culture findings. Results suggested that data from a homogeneous Native American sample poorly fit factor solutions reported from heterogeneous Native American and Caucasian samples, and favored a unifactorial solution. Implications for assessment with Native American peoples are discussed.     

Differential fan effect and attentional focus

As people study more facts about a concept, it takes longer to retrieve a particular fact about that concept. This fan effect (Anderson, 1974) has been attributed to competition among associations to a concept. Alternatively, the mental-model theory (Radvansky & Zacks, 1991) suggests that the fan effect disappears when the related concepts are organized into a single mental model. In the present study, attentional focus was manipulated to affect the mental model to be constructed. One group of participants focused on the person dimension of personlocation pairs, whereas the other group focused on the location dimension. The result showed that the fan effect with the focused dimension was greater than the fan effect with the nonfocused dimension, which is contrary to the mental-model theory. The number of associations with a concept is indeed crucial during retrieval, and the importance of the information seems to be accentuated with attentional focus.     

Attention to combined attention in new world monkeys (Cebus apella, Saimiri sciureus)

Co-orientation by capuchin (Cebus apella) and squirrel (Saimiri sciureus) monkeys in response to familiar humans abruptly switching the direction of their visual attention was recorded. Co-orientation occurred more frequently overall in capuchins than squirrel monkeys. Capuchins showed a tendency to habituate within trials involving consecutive attention switches performed by 2 different people, whereas squirrel monkeys co-oriented more when the 2nd attention switch was by a 2nd actor. These results suggest variable attention-processing abilities in New World monkeys, including differences in summation of attention by others.     

Evaluation of third-party reciprocity by squirrel monkeys (<Emphasis Type="Italic">Saimiri sciureus</Emphasis>) and the question of mechanisms

Social evaluation during third-party interactions emerges early in human ontogeny, and it has been shown in adult capuchin monkeys who witness violations of reciprocity in object exchanges: Monkeys were less inclined to accept food from humans who refused to reciprocate with another human. A recent study reporting similar evidence in marmoset monkeys raised the possibility that such evaluations might be based on species’ inherent cooperativeness. We tested a species not renowned for cooperativeness—squirrel monkeys—using the procedure used with marmosets and found a similar result. This finding rules out any crucial role for cooperative tendencies in monkeys’ responses to unfair exchanges. We then tested squirrel monkeys using procedures more similar to those used in the original study with capuchins. Squirrel monkeys again accepted food less frequently from non-reciprocators, but unlike capuchins, they also strongly preferred reciprocators. We conclude that neither squirrel monkeys nor marmoset monkeys engaged in emotional bookkeeping of the type that probably underlies social evaluation in capuchin monkeys; instead, they employed one or more simple behavioral rules. Further comparative studies are required to clarify the mechanisms underlying social evaluation processes across species.     

Motion influences gaze direction discrimination and disambiguates contradictory luminance cues

In two experiments, we investigated the role of apparent motion in discriminating left/right gaze deviation judgments. We demonstrated that discrimination accuracy and response confidence was significantly higher when the eyes were moved to the left or right, compared to when the eyes were presented in their final shifted position (static images). To dissociate the role of motion signals from luminance signals, gaze stimuli were also presented in reverse contrast. Replicating past studies polarity reversal had a profound and detrimental effect on gaze discrimination in static images, although, intriguingly, while response confidence remained low, participant performance improved as gaze angle increased. In striking contrast to these data, polarity reversal had no negative effect on performance when the eyes were moved. We discuss these findings in the context of a multiple-cue account of gaze perception.     

The Factor Structure of Gambling-Related Cognitions in an Undergraduate University Sample

Gambling is relatively common among university students, but few studies examine factors that contribute to gambling behavior in this cohort. Based on evidence that cognitive distortions may play a role in gambling behavior, this study examined the factor structure of gambling-related cognitive distortions using the Gambler’s Beliefs Questionnaire (GBQ; Steenbergh et al., Psychology of Addictive Behaviors, 16:143–149, 2002) in a sample of 393 college undergraduates. Confirmatory factor analysis was used to test a previously reported two-factor model, comprising dimensions of Illusion of Control (IOC) and Luck/Perseverance (L/P). An oblique, but not orthogonal, two-factor model was confirmed but did not provide an incrementally better fit to the data than a one-factor model. However, multiple regression analyses showed that the L/P scale accounted for significant variance in the criterion when controlling for IOC items. This suggests that IOC items provide redundant information and that gambling-related cognitive distortions in this sample can be adequately assessed using solely the L/P factor.

A central circuit of the mind

The methodologies of cognitive architectures and functional magnetic resonance imaging can mutually inform each other. For example, four modules of the ACT-R (adaptive control of thought - rational) cognitive architecture have been associated with four brain regions that are active in complex tasks. Activity in a lateral inferior prefrontal region reflects retrieval of information in a declarative module; activity in a posterior parietal region reflects changes to problem representations in an imaginal module; activity in the anterior cingulate cortex reflects the updates of control information in a goal module; and activity in the caudate nucleus reflects execution of productions in a procedural module. Differential patterns of activation in such central regions can reveal the time course of different components of complex cognition.
