Accuracy of judging others’ traits and states: Comparing mean levels across tests

Tests of accuracy in interpersonal perception take many forms. Often, such tests use designs and scoring methods that produce overall accuracy levels that cannot be directly compared across tests. Therefore, progress in understanding accuracy levels has been hampered. The present article employed several techniques for achieving score equivalency. Mean accuracy was converted to a common metric, pi [Rosenthal, R., & Rubin, D. B. (1989). Effect size estimation for one-sample multiple-choice-type data: Design, analysis, and meta-analysis. Psychological Bulletin, 106, 332–337] in a database of 109 published results representing tests that varied in terms of scoring method (proportion accuracy versus correlation), content (e.g., personality versus affect), number of response options, item preselection, cue channel (e.g., face versus voice), stimulus duration, and dynamism. Overall, accuracy was midway between guessing level and a perfect score, with accuracy being higher for tests based on preselected than unselected stimuli. When item preselection was held constant, accuracy was equivalent for judging affect and judging personality. However, comparisons must be made with caution due to methodological variations between studies and gaps in the literature.     

On the role of regular phonological variation in lexical access: evidence from voice assimilation in French

The present study investigated whether lexical access is affected by a regular phonological variation in connected speech: voice assimilation in French. Two associative priming experiments were conducted to determine whether strongly assimilated, potentially ambiguous word forms activate the conceptual representation of the underlying word. Would the ambiguous word form [sud] (either assimilated soute 'hold' or soude 'soda') facilitate "bagage" 'luggage', which is semantically related to soute but not to soude? In Experiment 1, words in either canonical or strongly assimilated form were presented as primes. Both forms primed their related target to the same extent. Potential lexical ambiguity did not modulate priming effects. In Experiment 2, the primes such as assimilated soute pronounced [sud] used in Experiment 1 were replaced with primes such as soude canonically pronounced [sud]. No semantic priming effect was obtained with these primes. Therefore, the effect observed for assimilated forms in Experiment 1 cannot be due to overall phonological proximity between canonical and assimilated forms. We propose that listeners must recover the intended words behind the assimilated forms through the exploitation of the remaining traces of the underlying form, however subtle these traces may be.     

Risky sexual behavior among married alcoholic men.

The current study explored whether the wives of men entering alcoholism treatment are at risk for sexually transmitted infections (STIs) exposure as a result of their husbands' sexual risk behaviors. The extramarital relationships of married alcoholic men entering outpatient treatment (n = 125) were compared with those of a demographically matched community sample of nonalcoholic married men (n = 125). The proportion of alcoholic men who reported 1 or more extramarital affairs in the previous year (14%) was significantly higher than that of the community sample (4%). Additionally, only 2 alcoholic husbands and 1 nonalcoholic husband reported that his wife was aware of the extramarital relationship. For both groups, none of the men who engaged in extramarital relationships reported consistent use of condoms when having sexual intercourse with their wives or with their extramarital partners. These results suggest that wives of alcoholic men are unknowingly placed at risk for indirect exposure to STIs as a result of their husbands' sexual risk behaviors. Thus, infidelity in treatment-seeking alcohol-abusing men represents a significant public health issue.     

NONVERBAL BEHAVIOR, STATUS, AND GENDER: HOW DO WE UNDERSTAND THEIR RELATIONS?

The causes of gender differences in nonverbal behavior are not well understood. The present article discusses status as a possible explanation and analyzes some of the methodological and conceptual challenges associated with testing that hypothesis. The study by Helweg-Larsen, Cunningham, Carrico, and Pergram (2004) , which investigated gender in relation to nodding toward peers versus professors in college classes, is highlighted to demonstrate some of the difficulties facing researchers when testing the status explanation.     

Attributing the sources of accuracy in unequal-power dyadic communication: Who is better and why?

A study was conducted to assess accuracy of deliberate nonverbal communication of affective messages between individuals assigned to different power roles within dyads. In phase 1, participants (N = 158) were assigned to unequal- or to equal-power roles and asked to send positive, negative, and neutral messages to their partner using nonverbal cues while the partner guessed which kind of message it was. In phase 2, naïve decoders (N = 294) made judgments of the videotapes from phase 1 to resolve the confounding of sender and decoder factors in the within-dyad communication paradigm. Results showed that subordinates were more accurate at decoding superiors than vice versa, and that this difference was due to subordinates sending less clear messages to superiors than superiors sent to subordinates. Comparison with the equal-power group’s expressions revealed that the subordinates’ expressions were also less clear than those sent by the equal-power group.

THE DEFENSIVE NATURE OF BENEFIT FINDING DURING ONGOING TERRORISM: AN EXAMINATION OF A NATIONAL SAMPLE OF ISRAELI JEWS

A study examining the effects of terrorism on a national sample of 1,136 Jewish adults was conducted in Israel via telephone surveys, during the Second Intifada. The relationship between reports of positive changes occurring subsequent to terrorism exposure (i.e., Benefit finding), posttraumatic stress disorder (PTSD) symptom severity, and negative outgroup attitudes toward Palestinian citizens of Israel (PCI) was examined. Benefit finding was related to greater PTSD symptom severity. Further, Benefit finding was related to greater threat perception of PCI and ethnic exclusionism of PCI. Findings were consistent with hypotheses derived from theories of outgroup bias and support the anxiety buffering role of social affiliation posited by terror management theory. This study suggests that benefit finding may be a defensive coping strategy when expressed under the conditions of ongoing terrorism and external threat.     

Semantic Compositionality and Truth-Conditional Content

It is widely held that hearers grasp an utterance's truth conditions by assigning contents to the linguistic expressions used, and combining these contents according to semantic composition rules. To preserve compositionality of truth-conditional content while accounting for context-sensitivity that is not traceable to overt linguistic form, semanticists posit covert linguistic structure. The strongest justification for this approach is the allegedly unconstrained nature of the alternative, whereby a process of 'free pragmatic enrichment' supplies constituents of content that are not traceable to (overt or covert) encoded meaning. This paper argues that free enrichment is tightly constrained by purely pragmatic factors, thus undermining the motivation for semantic compositionality.     

Left gaze bias in humans, rhesus monkeys and domestic dogs

While viewing faces, human adults often demonstrate a natural gaze bias towards the left visual field, that is, the right side of the viewee’s face is often inspected first and for longer periods. Using a preferential looking paradigm, we demonstrate that this bias is neither uniquely human nor limited to primates, and provide evidence to help elucidate its biological function within a broader social cognitive framework. We observed that 6-month-old infants showed a wider tendency for left gaze preference towards objects and faces of different species and orientation, while in adults the bias appears only towards upright human faces. Rhesus monkeys showed a left gaze bias towards upright human and monkey faces, but not towards inverted faces. Domestic dogs, however, only demonstrated a left gaze bias towards human faces, but not towards monkey or dog faces, nor to inanimate object images. Our findings suggest that face- and species-sensitive gaze asymmetry is more widespread in the animal kingdom than previously recognised, is not constrained by attentional or scanning bias, and could be shaped by experience to develop adaptive behavioural significance.
