Validating a distinction between primary and secondary psychopathy with measures of Gray's BIS and BAS constructs

Investigators commonly distinguish between primary and secondary psychopathy (H. Cleckley, 1976; D.T. Lykken, 1995), though there is a lack of consensus regarding the best means to achieve this distinction. To address the validity of using R. D. Hare's (2003) Psychopathy Checklist and the G. Welsh (1956) Anxiety Scale for this purpose, the authors used 2 measures of J. A. Gray's (1987) behavioral inhibition system/behavioral activation system (BIS/BAS). Following D. T. Lykken (1995) and D. C. Fowles (1980), the authors hypothesized that primary psychopathy would be associated with a weak BIS and a normal BAS, whereas secondary psychopathy would be associated with a strong BAS and a normal BIS. Results for primary psychopathy were as predicted. Results for secondary psychopathy clearly supported the strong BAS prediction but provided mixed support for the normal BIS prediction.     

Caught in the act: When impressions based on highly diagnostic behaviours are resistant to contradiction

Research and theory emphasizing the role of cue diagnosticity in judgment (e.g. Skowronski and Carlston, 1987, 1989) suggests that under the proper conditions: (a) negativity effects should be observed in judgments of honesty/dishonesty; (b) positivity effects should be observed in judgments of intelligence/unintelligence, and (c) intelligence-implicative and dishonesty-implicative cues should be increasingly difficult to contradict as those cues become more extreme. Two experiments yielded data consistent with these predictions. In addition, two other important findings emerged from these studies. The results of Experiments 1 and 2 indicated that subjects do not respond as if highly diagnostic cues are sufficient for category membership, suggesting that the representational format of trait categories does not correspond to the format suggested by the ‘classical model’ of categorization. The results of Experiment 2 also indicated that negativity and positivity effects are not substantially altered by a role-playing manipulation designed to increase subjects' involvement in the judgment task.     

The recall and use of traits and events in social inference processes

Social inference research needs to more closely examine the kinds of information people actually have available for making social judgments. It is assumed here that the observation of behavioral events results in encoding and storage of both a relatively raw event record and of higher level encodings, such as trait inferences. Several specific hypotheses are advanced concerning the effects of higher level encodings on event recall, and the effects of encoding and memory processes on subsequent judgments about a stimulus person. Consistent with hypotheses, results indicate that higher level encodings do affect recall for stimulus information and do affect judgments of the stimulus person. The possibility that higher level encodings affect judgments solely by introducing bias into recall for the episodic record is considered and discarded in favor of the interpretation that higher level encodings are actually recalled and used in inference processes.     

The validation of an active control intervention for Mindfulness Based Stress Reduction (MBSR)

Most of the extant literature investigating the health effects of mindfulness interventions relies on wait-list control comparisons. The current article specifies and validates an active control condition, the Health Enhancement Program (HEP), thus providing the foundation necessary for rigorous investigations of the relative efficacy of Mindfulness Based Stress Reduction (MBSR) and for testing mindfulness as an active ingredient. 63 participants were randomized to either MBSR (n = 31) or HEP (n = 32). Compared to HEP, MBSR led to reductions in thermal pain ratings in the mindfulness- but not the HEP-related instruction condition (η² = .18). There were significant improvements over time for general distress (η² = .09), anxiety (η² = .08), hostility (η² = .07), and medical symptoms (η² = .14), but no effects of intervention. Practice was not related to change. HEP is an active control condition for MBSR while remaining inert to mindfulness. These claims are supported by results from a pain task. Participant-reported outcomes (PROs) replicate previous improvements to well-being in MBSR, but indicate that MBSR is no more effective than a rigorous active control in improving these indices. These results emphasize the importance of using an active control condition like HEP in studies evaluating the effectiveness of MBSR.     

Seeing others through rose-colored glasses: An affiliation goal and positivity bias in implicit trait impressions

People infer traits from other people's behaviors without intention, awareness, or effort, and this spontaneous trait inference (STI) effect has been shown to be robust. The purpose of the present research was to demonstrate the flexibility of STIs despite the ubiquity. Specifically, we examined the effect of an affiliation goal on STI formation and found a positivity bias. In Experiment 1, perceivers with an affiliation goal formed more positive (versus negative) spontaneous trait inferences compared to those without this goal and those who had been primed with semantically positive, affiliation-unrelated words. Experiment 2 provided evidence that this effect was driven by a motivational state by showing that the positivity bias occurs only when a perceiver's goal to affiliate remains unfulfilled. The goal's interaction with trait valence showed focused, goal-relevant bias. These studies are the first to show that STIs form flexibly in response to perceivers' primed social goals supporting the functionality account of STIs in implicit impression formation.     

Assessing emotion sensitivity in female offenders with borderline personality symptoms: results from a fear-potentiated startle paradigm

An instructed fear-conditioning paradigm was used to measure fear-potentiated startle (FPS) in a sample of 80 Caucasian, female offenders assessed using the Personality Assessment Inventory-Borderline Features Scale (Morey, 1991). As predicted, women with higher levels of Borderline Personality Disorder (BPD) symptoms showed significantly greater FPS than women with lower levels when required to focus attention on the threat-relevant dimension of the experimental stimuli. However, FPS was not greater for women with higher levels of BPD symptoms in the two conditions that required participants to direct attention away from the threat-relevant dimension. These results highlight the importance of attention for moderating the association between BPD symptoms and exaggerated responses to threat-relevant information and may, therefore, help to resolve the inconsistent evidence on emotional reactivity in BPD. Moreover, the potential importance of attentional factors in BPD may shed new light on prominent symptoms of the disorder and existing theoretical perspectives on BPD.     

Inference making and linking both require thinking: Spontaneous trait inference and spontaneous trait transference both rely on working memory capacity

Past research suggests that spontaneous trait inference (STI) and spontaneous trait transference (STT) may reflect different cognitive processes, the former being inferential and the latter associational. The present research was designed to explore whether either or both of these processes involve thinking that occupies cognitive capacity. Four studies suggest that reductions in available cognitive capacity reduce both STI and STT effects, both on measures of savings in relearning (which reflect the strength of trait associations with a person) and on trait ratings measures (which reflect the strength of trait inferences made about a person). Similar results were obtained using an individual difference measure of cognitive capacity. Although these results suggest that STI and STT are similar, in that both exhibit interference from reductions in cognitive capacity, other results, such as halo effects in trait ratings, support previous assertions that their underlying processes are distinct.     

The effects of verbal and visual interference on impressions: An associated-systems approach

This study investigated associated-systems theory's prediction that interference with the visual or verbal mental systems should alter person impressions by removing or reducing the impact of the information represented within those systems, while accentuating the influence of other information. In Experiment 1, interference with the verbal system decreased the influence of verbal information on trait judgments and increased the influence of visual information on attractiveness and liking judgments. In Experiment 2, visual interference decreased the impact of visual information on attractiveness judgments and, at least for attractive targets, increased the impact of verbal information on trait and liking judgments. These results support the premise that impressions consist of representations allied with separate processing systems and that those impressions can be affected by other activities involving those systems.     

Relating derived relations as a model of analogical reasoning: reaction times and event-related potentials

The current study aimed to test a Relational Frame Theory (RFT) model of analogical reasoning based on the relating of derived same and derived difference relations. Experiment 1 recorded reaction time measures of similar-similar (e.g., "apple is to orange as dog is to cat") versus different-different (e.g., "he is to his brother as chalk is to cheese") derived relational responding, in both speed-contingent and speed-noncontingent conditions. Experiment 2 examined the event-related potentials (ERPs) associated with these two response patterns. Both experiments showed similar-similar responding to be significantly faster than different-different responding. Experiment 2 revealed significant differences between the waveforms of the two response patterns in the left-hemispheric prefrontal regions; different-different waveforms were significantly more negative than similar-similar waveforms. The behavioral and neurophysiological data support the RFT prediction that, all things being equal, similar-similar responding is relationally "simpler" than, and functionally distinct from, different-different analogical responding. The ERP data were fully consistent with findings in the neurocognitive literature on analogy. These findings strengthen the validity of the RFT model of analogical reasoning and supplement the behavior-analytic approach to analogy based on the relating of derived relations.
