Gender-role classification and demographic relationships: A function of type of scoring procedures

This study investigated the effect of different median split (combined-sex, single-sex, weighted, and unweighted) procedures on Bem Sex Role Inventory gender-role classifications and the effect of these procedures on demographic relationships. Results revealed significantly different gender-role classifications for all procedures except single-sex weighted and unweighted. No significant demographic relationships were found for men as a function of type of scoring procedures, but significant relationships for SES and marital status were found for women when single-sex weighted and unweighted median splits were used. Discussion focused on recommendations for further research using various median split procedures.     

Catastrophe theory: A topological reconceptualization of sexual orientation

The classical model of sexual orientation as a continuum is examined and hypotheses regarding the sequential patterning of sexual partner choices are considered. Data are reviewed which suggest that these patterns are often discontinuous: shifts from one orientation to the other are observed without a transitional period and bisexuality is rare as a lifestyle in which contacts with both male and female partners are regular, concurrent, ongoing activities. Catastrophe theory, a mathematical model of discontinuity, is explained with the simple example of aggression in dogs and then the simple cusp catastrophe is applied as a starting place for this topological reconceptualization of sexual orientation. Behavioral predictions and implications for future research are discussed.     

On spurious allusions

The criticisms of Walker’ theory by MacLeod, Virsu, and Carpenter are shown to stem from a too simple reading of the text of the theory, a failure to investigate fully the references cited to support their position, and an effort to bolster the theory of lateral inhibition in orientation detectors. The criticisms are shown to misrepresent the experimental data of various reports. Walker’s physiological premises are shown to be sound, and the cases of “contrary evidence” are shown infact to be in agreement with the theory. Lateral inhibition in orientation detectors as an explanation of optical illusions is shown to fail completely to agree with experimental results.     

Toward a Metacognitive Account of Cognitive Offloading

Individuals frequently make use of the body and environment when engaged in a cognitive task. For example, individuals will often spontaneously physically rotate when faced with rotated objects, such as an array of words, to putatively offload the performance costs associated with stimulus rotation. We looked to further examine this idea by independently manipulating the costs associated with both word rotation and array frame rotation. Surprisingly, we found that individuals’ patterns of spontaneous physical rotations did not follow patterns of performance costs or benefits associated with being physically rotated, findings difficult to reconcile with existing theories of strategy selection involving external resources. Individuals’ subjective ratings of perceived benefits, rather, provided an excellent match to the patterns of physical rotations, suggesting that the critical variable when deciding on‐the‐fly whether to incorporate an external resource is the participant's metacognitive beliefs regarding expected performance or the effort required for each approach (i.e., internal vs. internal + external). Implications for metacognition's future in theories of cognitive offloading are discussed.     

The role of perceived vulnerability to disease in political polarization on climate change

Climate change presents a serious threat to the planet. Previous research reveals an ingroup–outgroup effect in support for climate policies, with greater support by U.S. participants for policies ostensibly endorsed by their own political party, despite acceptance of climate change among most Republicans and Democrats. We investigated moderation of this effect by the behavioral immune system (BIS), a suite of psychological mechanisms that cause individuals to avoid pathogens. This system has been linked to more negative responses to outgroup members. We extended previous research examining effects on group polarization to political polarization. We predicted that support for climate change policies would show stronger effects of own-versus other-party endorsement among people higher in BIS, as indexed by perceived vulnerability to disease (PVD). We found that the ingroup–outgroup endorsement effect on policy support was moderated by PVD. However, the effect was opposite to prediction. Whereas low PVD participants showed less support for climate policies endorsed by the other party than their own, high PVD participants supported climate policies regardless of endorser. This unexpected result may be construed as consistent with high PVD individuals feeling heightened vulnerability to environmental threats, which fosters support for protective policies, regardless of endorser. We also found less support for climate policies among Republican than Democrat low PVD participants, but no party effect among high PVD participants. This suggests that feeling vulnerable to environmental threats may lead Republicans to deviate from the party norm in their support for climate policies.     

Not all visual features are created equal: early processing in letter and word recognition

In four experiments, we investigated the effect of deleting specific features of letters on letter and word recognition in the context of reading aloud. Experiments 1 and 2 assessed the relative importance of vertices versus midsegments in letter recognition. Experiments 3 and 4 tested the relative importance of vertices versus midsegments in word recognition. The results demonstrate that deleting vertices is more detrimental to letter and word identification than is deleting midsegments of letters. These results converge with those of previous research on the role of vertices in object identification. Theoretical implications for early processing in reading are noted.     

An Open Trial of an Acceptance-Based Behavioral Intervention for Weight Loss

Innovative approaches are urgently needed to improve behavioral treatment for weight loss. The weight regain that is so common after treatment may be a result of an environment that makes it challenging to adhere, long-term, to a dietary and physical activity regimen. This study was designed to test, via a 12-week open trial, the preliminary feasibility, acceptability, effectiveness, and possible mechanisms of action of a behavioral treatment that was modified to incorporate acceptance-based therapy components designed to (a) bolster participants’ commitment to behavior change, (b) build distress-tolerance skills, and (c) promote mindful awareness of eating behaviors and goals. Participants (n = 29) were overweight or obese women. Among completers (n = 19; 34% attrition), weight loss averaged 6.6% of body weight at posttreatment and 9.6% at 6-month follow-up (n = 14; 52% attrition). Intention-to-treat weight losses were 4.5% at posttreatment and 6.6% at 6-month follow-up. Psychological variables targeted by the intervention (e.g., cognitive restraint, disinhibition, urge-related eating behavior, emotional eating, eating-related experiential acceptance, mindfulness and motivation) changed in the expected directions, and many of these changes were consistent with decreases in weight loss. Moreover, despite the limitations of the single-group design, this pilot study demonstrated the preliminary feasibility, acceptability, and effectiveness of a novel, acceptance-based behavioral treatment for obesity. One potential implication is that behaviorally based weight loss interventions might be improved by overlaying an acceptance-based framework.
