Miserliness in human cognition: the interaction of detection,override and mindware

ABSTRACT

Humans are cognitive misers because their basic tendency is to default to processing mechanisms of low computational expense. Such a tendency leads to suboptimal outcomes in certain types of hostile environments. The theoretical inferences made from correct and incorrect responding on heuristics and biases tasks have been overly simplified, however. The framework developed here traces the complexities inherent in these tasks by identifying five processing states that are possible in most heuristics and biases tasks. The framework also identifies three possible processing defects: inadequately learned mindware; failure to detect the necessity of overriding the miserly response; and failure to sustain the override process once initiated. An important insight gained from using the framework is that degree of mindware instantiation is strongly related to the probability of successful detection and override. Thus, errors on such tasks cannot be unambiguously attributed to miserly processing – and correct responses are not necessarily the result of computationally expensive cognition.     

The Cognitive Reflection Test as a predictor of performance on heuristics-and-biases tasks

The Cognitive Reflection Test (CRT; Frederick, 2005) is designed to measure the tendency to override a prepotent response alternative that is incorrect and to engage in further reflection that leads to the correct response. In this study, we showed that the CRT is a more potent predictor of performance on a wide sample of tasks from the heuristics-and-biases literature than measures of cognitive ability, thinking dispositions, and executive functioning. Although the CRT has a substantial correlation with cognitive ability, a series of regression analyses indicated that the CRT was a unique predictor of performance on heuristics-and-biases tasks. It accounted for substantial additional variance after the other measures of individual differences had been statistically controlled. We conjecture that this is because neither intelligence tests nor measures of executive functioning assess the tendency toward miserly processing in the way that the CRT does. We argue that the CRT is a particularly potent measure of the tendency toward miserly processing because it is a performance measure rather than a self-report measure.

The relationship between induced emotional arousal and amnesia

An experiment was conducted to test a hypothesis emanating from a similarity in data pattern between studies on amnesia and studies on the effects of arousal on memory. The hypothesis was that arousal and amnesia might be related, or more precisely, that amnesia induced in the laboratory might be mediated by high levels of arousal. Subjects in this experiment were presented with a thematic, short story in pictorial form. One version of the story consisted of a traumatic, arousal-inducing event placed between neutral events. A second version of the story contained the same neutral events in the beginning and the end, but also a neutral event in the middle. Palmar skin conductance, heart rate, and subjective self-ratings were used to determine that the manipulation made had caused different degrees of emotional arousal for the two groups of subjects presented with the different versions of the story. The methods used to determine memory performance were recall and recognition. The data obtained indicate that amnesia induced in the laboratory is mediated by emotional arousal in terms of concepts of attention and reconstruction.     

Reactions to DMT as related to psychotic and borderline personality organization

Thirty-one inpatients in a psychiatric clinic were assessed with DMT and the Structural Interview. In order to assemble every relevant reaction that an individual might have to a percept-genesis, 130 DMT variables were formed. The results were first subjected to a quality control of the DMT-scores and then subjected to partial least squares in latent variables (PLS) discriminant analysis. The analysis showed that it is possible to separate patients with psychotic PO (PPO) from those with borderline PO (BPO) by means of the 130 variables. The BPO group is characterized by aggressive manifestations, sensitivity to threat, identity lability and various transformations of the Hero gestalt. The PPO group, on the other hand, is characterized by high threshold values for perception, lack of identity, denial and repression of the peripheral person at a late-phase level. There are other perceptual reactions that are important predictors of PO than the defence categories of the manual. These perceptual reactions do not correspond to the traditional psychodynamic defence mechanisms. Our conclusion is that principal component analysis (PCA) and PLS are useful methods of finding discriminating patterns of perceptual reactions to the DMT for patients with different PO.     

Initial memory deficits and subsequent recovery in two cases of head trauma

This study describes initial and one-year follow-up findings on verbal memory testing of two patients who sustained moderate head injuries. The two main purposes were (a) to capture the specific patterns of memory disorders shown by these two head-trauma patients, and (b) to explore the nature of the recovery of these disorders. Several episodic memory tests and semantic memory tests were employed as well as questions about autobiographical events having occurred prior to and after the trauma, and about various aspects of the accident itself causing the trauma. The main conclusions to be drawn from the study are that the memory disorders demonstrated are based on difficulties in memory organization, and that the two patients differ in the nature of the recovery of the deficits.     

Visual angle and the word superiority effect

Two experiments are reported in which a word superiority effect is obtained under conditions where a fixed set of alternatives are employed with positional certainty as to the critical letter, trial type (word or nonword) is mixed, and the subject is told to fixate the position of the critical letter. A third experiment employed the same methodology except for the fact that the stimuli subtended a larger retinal angle. No word superiority effect was observed in the third experiment. It is suggested that the visual angle of the stimulus display is a crucial factor in experiments on the word superiority effect.     

Cognitive sophistication does not attenuate the bias blind spot

The so-called bias blind spot arises when people report that thinking biases are more prevalent in others than in themselves. Bias turns out to be relatively easy to recognize in the behaviors of others, but often difficult to detect in one's own judgments. Most previous research on the bias blind spot has focused on bias in the social domain. In 2 studies, we found replicable bias blind spots with respect to many of the classic cognitive biases studied in the heuristics and biases literature (e.g., Tversky & Kahneman, 1974). Further, we found that none of these bias blind spots were attenuated by measures of cognitive sophistication such as cognitive ability or thinking dispositions related to bias. If anything, a larger bias blind spot was associated with higher cognitive ability. Additional analyses indicated that being free of the bias blind spot does not help a person avoid the actual classic cognitive biases. We discuss these findings in terms of a generic dual-process theory of cognition. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Dual process theory and the context of choice: Comments on Dhar and Gorlin

Dhar and Gorlin show that default-interventionist dual-process theory differentially classifies several effects in the consumer choice literature and makes differential predictions across a variety of manipulations. One of the most startling differential classifications in their model is that it drives a wedge between the attraction and enhancement effects, because they arise from System 1 and System 2, respectively. System-2 bias effects explain why sometimes less complex organisms (nonhumans, human children) can display more normative behavior than human adults. Such a finding does not at all undermine the heuristics and biases research tradition, as is sometimes argued.
