Checking the reliability and validity of HSPQ profiles

Developed a scale designed to detect invalid response patterns on the High School Personality Questionnaire (HSPQ). Using a large sample of protocols drawn from the HSPQ standardization group, ten items were found to satisfy the necessary criterion for inclusion in the resulting "random" or "validity" (RV) scale. When applied to separate cross-validation groups of nearly 2,000 valid and randomly generated response protocols, RV was found to correctly classify 79% of the profiles. As a further test of the scale's utility, 100 profiles classified as valid and 100 classified as invalid were selected for comparison. In the invalid group, KR-20 reliabilities of the 14 trait scales were almost uniformly lowered, Also, for the invalid group the correlations among the trait scales were attenuated and altered to the extent that the underlying factor structure of the test was upset.     

Subliminal priming and effects of hand dominance

In the masked priming paradigm, motor responses to targets are influenced by previously presented subliminal primes, and are guided by facilitatory and inhibitory mechanisms that depend on prime-target compatibility/duration. In this study, we evaluate subliminal-driven priming in right- and left-handers during unimanual as well as bimanual tasks. The data from the unimanual tasks confirmed that prime-target compatibility affects performance as a function of prime-target duration. In a bimanual setting, the preferred hand benefitted from facilitation in both handedness groups whereas the non-preferred hand showed a positive priming effect only in left-handers. This denotes that left-handers are more susceptible to response activation of either hand. In addition, inhibitory priming had a stronger effect on the non-preferred than preferred hand, independent of handedness group. Overall, the findings suggest that subliminal-driven mechanisms that assist adaptive motor behavior are sensitive not only to extrinsic (task-related) factors such as prime-target compatibility but also to intrinsic (performer-related) factors such as hand dominance. The data further provide support for handedness-specific effects in motor functions and underline a significant role of hand dominance in the control of bimanual actions.     

Specificity of episodic and semantic aspects of autobiographical memory in relation to symptoms of posttraumatic stress disorder (PTSD)

Two studies examined the relationship between the ability to access specific autobiographical material in memory and presence/symptoms of posttraumatic stress. In Study 1, a sample of refugees with a diagnosis of posttraumatic stress disorder (PTSD) completed the Autobiographical Memory Test (AMT) in which they had to generate specific episodic autobiographical memories in response to emotion-related cue words. Results showed that reduced specificity of memories on the AMT was associated with an increased frequency of trauma-related flashbacks but with reduced use of effortful avoidance to deal with trauma-related intrusions in the day-to-day. Study 2 examined retrieval of semantic autobiographical information from previous lifetime periods in groups of cancer survivors with posttraumatic stress and healthy controls. The cancer survivors were able to generate fewer specific semantic details about the personal past compared to the controls. The more symptomatic survivors showed the greatest memory impairment. The data from both studies are discussed in terms of compromised access to specific autobiographical material in distressed trauma survivors reflecting a process of affect regulation.     

Style and substance in social desirability scales

The purpose of the present study was to examine the nature of a social desirability measure under two different types of instructions for filling out personality questionnaires in an occupational selection setting. 1230 male applicants for public vehicle driving licences were administered Cattett's 16PF and the Eysenck Personality Questionnaire (EPQ). The subjects were randomly assigned to two groups. One was given standard instructions for filling out these questionnaires; the second was given special instructions designed to reduce social desirability response bias. Social desirability was indexed by the Lie scale of the EPQ. Based on Eysenck's theorizing concerning the meaning of the Lie scale, the following hypothesis was tested: the factorial location of the Lie scale in the personality domain will differ under the two forms of instructions. It should appear separately from other personality factors under the standard instructions, whereas under the special instructions it should be subsumed under the personality factor which measures conformity. The results supported this hypothesis. The discussion focuses on the meaning of the Lie scale under conditions that elicit social desirability bias and on the role of special instructions in reducing this bias.

Changing False Beliefs from Repeated Advertising: The Role of Claim‐Refutation Alignment

This research addresses refutation of false beliefs formed on the basis of repeated exposure to advertisements. Experiment 1 explores belief in the refutation as a function of the perceptual details shared (alignment) between the claim and the refutation as manipulated by whether the original claim was direct (assertion) or indirect (implication). Experiment 2 then examines whether this effect will carry through to belief in the original claim after exposure to the refutation. Findings indicate that direct refutations of indirect claims are believed more than refutations of direct claims. However, direct refutations of direct claims are more effective in reducing belief in the original claim. We argue that recollection of the original claim facilitates automatic updating of belief in that claim. Experiment 3 demonstrates that an alternative cue (a logo) in a refutation that facilitates recall of the original claim enables reduction of belief in the original indirect claim; this finding helps to pin down the mechanism—recall of the original claim—underlying belief updating. Further, Experiment 3 finds that multiple cues to recalling the original claim may prevent the automatic updating process. Theoretical and practical implications are discussed.     

Assessing Agreement between the K10 and MHI-5 Measures of Psychological Wellbeing

Responses to the Kessler Psychological Distress Scale (K10) and the Mental Health Index-5 (MHI-5) mental health subscale of the Medical Outcomes Study Short Form (SF-36) survey cover broadly similar constructs. The aim of this paper is to use the equipercentile method to produce a concordance between K10 and MHI-5 across the whole score distribution. Comparisons were made using survey data from the Australian Longitudinal Study on Women’s Health (ALSWH) and the Household, Income and Labour Dynamics in Australia (HILDA) survey, which used both the K10 and the MHI-5 measures at the same time for the same participants. Agreement was assessed with Bland-Altman plots. The differences between MHI-5 scores and transformed K10 scores were assessed with paired t-tests. For the ALSWH data there is good agreement between MHI-5 scores and scores equated from the K10. The mean of the differences is −0.15 with standard deviation 10.8. Using the ALSWH transformation on the HILDA data for different age groups and genders, the mean differences ranged from 0.43 to 3.38 with corresponding standard deviations of 11.1 to 9.9. The concordance table was very similar to one obtained by the more complicated item response theory method. The results suggest that longitudinal surveys of the same respondents that previously used MHI-5 could adopt the K10 (or vice versa) without loss of comparability.

     

Indulgence as self‐reward for prior shopping restraint: A justification‐based mechanism

This research investigates the effects of refraining from a purchase temptation at one point in time on choices made at a subsequent opportunity to purchase or consume a tempting product. Four experiments involving scenarios and real decisions demonstrate that the salience of restraint at a prior impulse buying opportunity causes consumers to reward themselves subsequently by choosing indulgence over non-indulgence. We show that indulgence is likely to increase only when prior restraint is salient and hence can be used as a justification. As expected, an index of reasons for vs. against buying mediates the relationship between prior impulse purchase decision and indulgent choice. In further support of the mechanism, we find that prior indulgence can have the same effect as prior restraint, if the prior indulgence is made justifiable. Finally, we show that prior shopping restraint can increase indulgence without a corresponding increase in self-esteem. These findings extend our understanding of self-regulation and demonstrate that everyday consumer decisions such as responses to impulse buying opportunities can have consequential downstream effects.     

Untangling the web of misinformation and false beliefs

Stanley et al. (2022) underscore four fundamental cognitive principles that underlie the human belief system. These include the truth bias (a predisposition to believe incoming information as true), bias to extract meaning from information (use of prior expectations to make sense of new information), bias to rely on the source of information to judge truth (using judgments of source credibility to rate veracity), and bias to rely on fluency to judge truth (perceptions of ease of processing information affect truth judgments). I suggest that understanding these principles can help us defer and deflect false beliefs from becoming entrenched in consumer minds and offer ways to leverage the four principles in the service of truth. I then propose that we broaden our focus in the study of false beliefs in three ways--by focusing on prevention of false beliefs rather than correction, by diversifying the dependent measures we study and by addressing the role of identity in false belief maintenance. I conclude with a discussion of some thorny issues and the need for regulation in this sphere. I seek to offer a research agenda to scholars interested in addressing the misinformation crisis that is ripping apart the fabric of our society.
