The role of personality in crowding research

An analysis of variance was carried out on Ss who were tested with a letter-cancellation task under four experimental conditions, two levels each of crowding and disconfirmation of expectancy. Eight types of Ss were distinguished based on sex and high or low scores on E and N. The crowding situation and disconfirmation of expectancy was found to affect extraverts significantly more than introverts, as predicted by the Brebner-Cooper model. It was confirmed that personality is an important variable in crowding research.     

Alcohol as social lubricant.

This study examines how consuming alcohol differentially affects the communicative behavior and perceptions of high and low social self‐esteem (SSE) women as they engage in a brief interaction with a flirtatious male. Alcohol myopia theory proposes that alcohol affects behavior when it blocks a person's normal inhibitions about enacting a behavior. It was predicted that low SSE women would be more inhibited when talking to a flirtatious male than would high SSE women and, therefore administration of a social self‐esteem measure and random assignment to an alcoholic or nonalcoholic beverage condition, participants (N=50) talked with an attractive, flirtatious male confederate. Low SSE women were less anxious and self‐disclosed more when drinking than when sober, whereas high SSE women were not significantly affected by alcohol consumption. The discussion highlights the complex and often contradictory effects of alcohol consumption on social interaction.     

S-R compatibility and changes in RT with practice

A visual, two-choice RT experiment was performed to assess the effect of practice on compatibility effects. The data are interpreted as showing that identification of the position of the hand gradually becomes independent of the hand's normal side.Further analysis suggests that “compatible” or “natural” relationships are those in which a single recoding process can be successfully applied to all the relevant spatial relationships. This gives rise to the further prediction that where all relationships are uniformly “incompatible”, performance will be better than where there is a mixture of “compatible” and “incompatible” relationships.     

Dude looks like a lady: Exploring the malleability of person categorization

Recent research has documented how single facial features can trigger person categorization. Questions remain, however, regarding the automaticity of the reported effects. Using a modified flanker paradigm, the current investigation explored the extent to which hair cues drive sex categorization when faces comprise task‐irrelevant (i.e., unattended) stimuli. In three experiments, participants were required to classify target forenames by gender while ignoring irrelevant flanking faces with and without hair cues. When present, hair cues were either congruent or incongruent with prevailing cultural stereotypes. The results demonstrated the potency of category‐specifying featural cues. First, flanker interference only emerged when critical hair cues were present (Experiment 1). Second, flankers with stereotype‐incongruent hairstyles (e.g., men with long hair) facilitated access to information associated with the opposite sex (Experiment 2), even when the flankers were highly familiar celebrities (Experiment 3). The theoretical implications of these findings are considered. Copyright © 2009 John Wiley & Sons, Ltd.     

Ensemble size and selective response times with a constant signal rate

Using a selective response task in which subjects were required to respond only to one of a number of alternative digits, although signal rate was held constant, the latency of selective responses was found to lengthen as the number of alternatives increased. This finding does not support the inference drawn from the work of Mowbray (1960) that, with signal rate held constant, there should be no significant lengthening of reaction times as the ensemble of digits increases.     

Stimulus- or response-induced excitation. A comparison of the behavior of introverts and extraverts

The tendency to inspect visual material (slides) rather than to respond by pressing a key in an attempt to move on to the next slide, was compared among introverts and extraverts. As predicted from Brebner and Cooper (1974): (1) extraverts inspected the stimuli for a shorter time before making their first response, (2) extraverts made more responses at a faster rate than introverts did, and (3) extraverts produced a significantly higher proportion of runs of accelerating responses.     

The Rusalov Structure of Temperament Questionnaire (STQ): results from an Australian sample

Recently, a new temperament inventory [the Rusalov Structure of Temperament Questionnaire (STQ)] has been developed to account for advances in theoretical models of basic central nervous system processes. Rusalov has hypothesized that temperament consists of 8 dimensions; 4 object and 4 subject related interactions. Australian data is presented, suggesting good agreement between the STQ results in the Australian and Russian samples. Generally, internal reliability was adequate for questionnaire responses.     

A cross-cultural replication of attitudes to the physical environment

A replication of Winkel et al.'s (1969) factor analytic study of attitudes to the U.S.A. physical environment was undertaken in Australia. A questionnaire on reactions to the environment was given to 303 South Australian adults. Three factors similar to those identified by Winkel et al. in the U.S.A. were found. However, the method of factor identification used in the present study allowed clearer interpretation and specification of the dimensions. Three additional factors reflecting individual attitudes towards the environment were also distinguished.
