Comparative Optimism and Event Skewness

Comparative judgment biases—wherein a majority of people report being above‐ or below‐average in their abilities, traits, or future events—are a robust phenomenon in psychology. A recent explanation for these biases has focused on people's awareness that many comparative judgment domains form skewed distributions, and, hence, a majority of people can feasibly be above or below average. Indeed, this prior research found that comparative biases for abilities emerged more for skewed (vs. normal) distributions. In the current research, we attempted to (i) conceptually replicate this finding in a comparative likelihood context and (ii) provide evidence of an alternative explanation for the prior results. Replicating prior research, three correlational studies and one experimental study found that event skewness was related to direct comparative likelihood judgments for health events, such that comparative optimism emerged more for events judged or manipulated to come from positively skewed distributions than from negatively skewed distributions. However, event skewness was unrelated to indirect comparisons (absolute self minus absolute other). Moreover, consistent with an egocentric‐processes account, absolute self‐judgments were more predictive of direct comparisons than were absolute other judgments and showed the same association with event skewness as direct comparisons. Implications for explaining and interpreting comparative judgment biases are discussed. Copyright © 2016 John Wiley & Sons, Ltd.

"Boys don't cry": examination of the links between endorsement of masculine norms, self-stigma, and help-seeking attitudes for men from diverse backgrounds

The role of conformity to dominant U.S. masculine norms as an antecedent to help-seeking attitudes in men has been established using convenience samples made up largely of college-age and European American males. However, the role of conformity to masculine norms on help-seeking attitudes for noncollege-age men or for men from diverse backgrounds is not well understood. To fill this gap in the literature, the present study examined the cross-cultural relevance of a mediational model of the relationships between conformity to dominant U.S. masculine norms and attitudes toward counseling through the mediator of self-stigma of seeking counseling for 4,773 men from both majority and nonmajority populations (race/ethnicity and sexual orientation). Structural equation modeling results showed that the model established using college males from majority groups (European American, heterosexual) may be applicable to a community sample of males from differing racial/ethnic groups and sexual orientations. However, some important differences in the presence and strengths of the relationships between conformity to dominant masculine norms and the other variables in the model were present across different racial/ethnic groups and sexual orientations. These findings suggest the need to pay specific theoretical and clinical attention to how conformity to dominant masculine norms and self-stigma are linked to unfavorable attitudes toward help seeking for these men, in order to encourage underserved men's help-seeking behavior.     

Role of cerebellum in fine speech control in childhood: persistent dysarthria after surgical treatment for posterior fossa tumour

Dysarthria following surgical resection of childhood posterior fossa tumour (PFT) is most commonly documented in a select group of participants with mutism in the acute recovery phase, thus limiting knowledge of post-operative prognosis for this population of children as a whole. Here we report on the speech characteristics of 13 cases seen long-term after surgical treatment for childhood PFT, unselected for the presence of post-operative mutism (mean time post-surgery = 6y10 m, range 1;4-12;6 years, two had post-operative mutism), and examine factors affecting outcome. Twenty-six age- and sex- matched healthy controls were recruited for comparison. Participants in both groups had speech assessments using detailed perceptual and acoustic methods. Over two-thirds of the group (69%) with removal of PFT had a profile of typically mild dysarthria. Prominent speech deficits included consonant imprecision, reduced rate, monopitch and monoloudness. We conclude that speech deficits may persist even up to 10 years post-surgery in participants who have not shown mutism in the acute phase. Of cases with unilateral lesions, poorer outcomes were associated with right cerebellar tumours compared to left, consistent with the notion based on adult data that speech is controlled by reciprocal right cerebellar/left frontal interactions. These results confirm the important role of the cerebellum in the control of fine speech movements in children.     

Mental Health Stereotypes About Gay Men

Three studies were conducted to examine the mental health stereotypes about gay men among college student and therapist trainee samples. Results from Study 1 indicated that (a) college students and therapist trainees endorsed a stereotype of the mental health of gay men that was similar in terms of its content and strength, and (b) the stereotype was consistent with five DSM-IV-TR disorder categories: mood, anxiety, sexual and gender identity, eating, and personality disorders. In Study 2 and 3 we investigated whether homophobia or a tendency to report cultural beliefs could account for the lack of difference between college students and therapist trainees. Results did not support either explanation.     

A public versus private administration of the implicit association test

This research includes two experiments that examined (a) whether the assessment situation in which individuals complete an implicit measure of bias alters their responses and (b) whether the hypothesized effect of the assessment situation on implicitly assessed bias reflects socially desirable responding. Participants in Experiment 1 (N = 151) completed an IAT measuring bias toward homosexuality in either a public or a private assessment situation. Consistent with studies of explicitly assessed attitudes, implicitly assessed bias toward homosexuality was significantly lower when assessed in a public versus a private assessment situation. Participants in Experiment 2 (N = 102) completed an IAT measuring bias toward homosexuality in a public assessment situation under a bogus pipeline or no‐bogus pipeline condition. Results indicated that participants' implicitly assessed bias did not significantly differ across these conditions. The authors discuss these findings in terms of possible automatic processes affecting the malleability of implicitly assessed attitudes. Copyright © 2006 John Wiley & Sons, Ltd.     

Evidence for frequency-based constituents in the mental lexicon: collocations involving the word of

In this paper, it is hypothesized that units larger than the traditional word, such as two-word collocations and phrases, may be stored in the mental lexicon and accessed holistically. Following previously published work on the Network or Usage-based model of lexical storage (Bybee, 1985, 1995), we suggest that the mechanism determining this constituency is the frequency with which items occur together in natural, connected speech: the collocational frequency. The present study uses a word-monitoring paradigm to investigate reaction times to the English function word of in collocations of varying levels of frequency. A significant effect of collocational frequency was observed; response latencies were longer when the target word of occurred in the very frequent collocations, indicating holistic processing of the frequent phrases. Furthermore, response latencies presented here are considerably longer than those reported in previous studies. This is explained as a result of the hypothesized holistic representation as well as a function of the use of stimuli extracted from natural conversation.     

Cerebral lateralization of spatial abilities: a meta-analysis

There is a substantial disagreement in the existing literature regarding which hemisphere of the brain controls spatial abilities. In an attempt to resolve this dispute, we conducted a meta-analysis to decipher which hemisphere truly dominates and under what circumstances. It was found that across people and situations, the right hemisphere is the more dominant for spatial processing. However, consideration of specific moderator variables yielded a more complex picture. For example, females showed no hemisphere preference while males showed a right hemisphere advantage. Also, no hemisphere preference was indicated for spatial visualization tasks while subjects performing spatial orientation and manual manipulation tasks displayed a predictable right hemisphere preference. These findings are discussed in terms of their implications for exiting theoretical positions as well as future empirical research.
