The roles of practice and correction in the categorization of sour and bitter taste qualities

Ten Ss were selected from a group of 40 screened to determine misnaming of stimuli usually called sour (hydrochloric and citric acid) and bitter (quinine sulfate). The 10 Ss were then given 16 trials in which they were asked to match the stimuli to standards, with or without verbal feedback for each stimulus. This was followed by 16 trials without feedback for all Ss and, several days later, by a 16-trial posttest. Final improved performance of the Ss was not affected by having received the feedback. It was concluded that experience with the stimuli leads to a reduction in the degree of misnaming, implying a nonphysiological basis for sour-bitter confusions.     

A device for facilitating the computation of the first four moments about the mean

A mechanical device is described which materially reduces the time, labor, and probability of errors which are involved in the computation of certain moments about the mean. The use of the device is illustrated with the computation of the mean, standard deviation,g ₁ as a measure of skewness, andg ₂ as a measure of kurtosis of data from a given study.Grateful acknowledgment is made to the Holter Research Foundation of Helena, Montana for the grant-in-aid which made possible the development of this device.     

Quantitative relations between avoidance behavior and pituitary-adrenal cortical activity

The rate at which monkeys pressed a lever and avoided shocks was manipulated in several ways. Measurements were also made of their plasma levels of 17-hydroxycorticosteroids. The rate at which the animals pressed the lever and the frequency with which they received shocks were both implicated as determiners of the steroid levels.     

Evidence for Context Switching in the Effects of Average Item Length and Item-Length Variability on Internal Consistency

This investigation examined the effects of 3 item characteristics—the average number of words per item, within-scale variability in item length, and item “direction”—on internal consistency reliability and interitem correlation. In Study 1, we examined the effects of these variables on overall scale-level reliability using 444 subscales from 9 personality scales. In Study 2, we examined interitem correlation at the paired-item level using 477 nonredundant item pairs from 14 personality scales. Lower scale reliability was associated with more average words per item, greater within-scale variability in item length, and a greater percentage of reverse-keyed items. Similarly, smaller interitem correlations were associated with a greater degree of mismatch in item length between the paired items and with a mismatch (vs. match) in the items' respective “directions.” The pattern of results across both studies supports our notion that lower internal consistency results from increased context switching; that is, from the confusion that occurs when respondents must switch back and forth between the interpretive frames pertaining to short versus long items, or between items pertaining to one pole of a personality dimension and its “opposite” pole. Suggestions for maximizing the internal consistency of personality scales are proposed.     

The Incremental Validity of the Trait Emotional Intelligence Questionnaire (TEIQue): A Systematic Review and Meta-Analysis

A criticism leveled against the conceptualization of emotional intelligence (EI) as a personality trait is that it overlaps considerably with the higher order personality dimensions and, therefore, has weak utility. To investigate this criticism, a systematic review and meta-analysis were conducted to synthesize the literature examining the incremental validity of the 2 adult self-report forms of the Trait Emotional Intelligence Questionnaire (TEIQue). Twenty-four articles reporting 114 incremental validity analyses of the TEIQue were reviewed according to the studies' methodological features. Additionally, data from 18 studies (providing 105 effect sizes) were pooled in a meta-analysis. Results suggest that the TEIQue consistently explains incremental variance in criteria pertaining to different areas of functioning, beyond higher order personality dimensions and other emotion-related variables. The pooled effect size was relatively small, but statistically and practically significant (ΔR² = .06, SE = .0116; 95% CI [.03, .08]). The number of covariates controlled for, the form of the TEIQue, and the focus on higher order personality dimensions versus other individual-difference constructs as baseline predictors did not affect the effect size. Analyses conducted at the factor level indicated that the incremental contribution is mainly due to the well-being and self-control factors of trait EI. Methodological issues and directions for future research are discussed.     

Sex Differences in Judgments of Social Desirability

This study evaluates sex differences in the perceived desirability of personality behaviors and beliefs. Men and women (N = 149, M_age = 18.7) judged the social desirability scale values (SDSVs) of 150 personality statements as applied either to a male target or a female target. For comparison, some estimated SDSVs with no target sex specified. A separate sample of 537 respondents endorsed the 150 items via self‐report. Raters showed a high consensus in their SDSV judgments within conditions (α = .86 to .90) and no sex‐of‐rater effects across conditions. Substantial sex‐of‐target effects (p < .001), however, revealed many behaviors that were viewed as desirable for one sex but not for the other. The behaviors seen as more (less) desirable when applied to men rather than to women were endorsed more (less) by men than by women in the respondent sample. Similar results were found when no target sex was specified for the SDSV ratings, presumably because judges evaluated the behaviors as applied to a target of their own sex. The present results have important implications for the measurement and reporting of SDSVs, the evaluation of substance versus style in self‐reports, and the construction of desirability‐reduced personality inventories.
