Effects of goal difficulty, self-set goals, and monetary rewards on dual task performance

The present study tests the effects of goal difficulty, goal origin (self-set vs assigned), and monetary rewards (present vs absent) on the simultaneous performance of two tasks (dual-task paradigm). Participants were 32 students working simultaneously on a computerized task of letter typing with the right hand and digit classification with the left hand. A 2 (self-set vs assigned goals) × 2 (present vs absent contingent monetary rewards) × 3 (easy, moderate, and difficult goals) factorial design with goal difficulty as the repeated factor was employed. Each task element was performed under easy, moderate, and difficult goals, which appeared in six consecutive trials of varied order within each experimental condition. Results indicate that self-set goals without monetary rewards led to the highest performance levels, whereas the combination of self-set goals and monetary rewards was detrimental to performance. These findings occurred (except in one case) only when goals were of either moderate Or high difficulty.     

Fostering a career in engineering

The purpose of the present study was to examine J. Holland's (Making vocational choices: a theory of careers, Englewood Cliffs, N.J.: Prentice-Hall, 1973) congruence hypothesis within the context of intraoccupational rather than interoccupational differences. One hundred and nine engineers were tested on an interest inventory which was designed to measure the vocational interest in six different job functions of the engineering occupation. Reliability coefficients range between .66 and .93. Results confirmed the congruence hypothesis: Correlations between job satisfaction and three measures derived from the interest inventory were .45, .44, and .62, respectively (p < .01). The theoretical and practical implications are discussed.     

Information-gathering strategies in hypothesis-testing

Three experiments were conducted to investigate the informational factors affecting the kinds of questions people ask for testing a hypothesis about another's personality. In Experiment 1, subjects formulated by themselves questions to test either the hypothesis that the interviewee is polite or the hypothesis that he is impolite. The boundary of the hypothesis was set either at an extreme or at an intermediate point on the trait dimension. Experiment 2 also varied the location of the boundary, but the hypotheses concerned extroversion-introversion and subjects chose questions from a predetermined list of questions that asked either about extroverted features or introverted features and that were either low or high in diagnostic value. Both studies found that subjects preferred to ask about features that are consistent with the hypothesis only when the boundary was extreme. In contrast, diagnostic features were preferred in all conditions. Experiment 3 showed that subjects' judgment of the diagnosticity of the various kinds of questions for discriminating at different boundaries paralleled subjects' preferences among these questions. These results were interpreted as providing support for the diagnostic strategy in social information gathering.     

Stimulus novelty and intraseries primacy in GSR adaptation

GSR records were obtained for four groups of 20 Ss. Group I was presented with a series of four different lights (amber, blue, green, and white) appearing 20 times each, in apparent random order. The procedure was similar for the other three groups except that in group 2, a novel stimulus (a red light) appeared instead of the sixth amber light; in group 3, it appeared instead of the 11th amber light; and, in group 4, it appeared instead of the 16th amber light. Typical GSR adaptation phenomena were observed in all groups. The introduction of the novel stimulus appeared to have no effect on the course of GSR adaptation.     

Children's perception of gender-role-congruent and -incongruent behavior in peers: Fisher-price meets price waterhouse

This study evaluated whether traditional gender-role stereotypes still pervade children's judgments of peers. One hundred seventy-three predominantly Caucasian, middle class boys and girls (ages 7 to 12) watched either a female or a male dyad discuss fundraising activities on videotape. In each dyad, one actor portrayed either masculine or feminine stereotyped behavior, whereas the other actor was neutral. Results indicated that performance judgments of a girl who behaves in a stereotypically masculine fashion are positive, but that personality ratings are more negative.     

Acute effects of triazolam on false recognition

Neuropsychological, neuroimaging, and electrophysiological techniques have been applied to the study of false recognition; however, psychopharmacological techniques have not been applied. Benzodiazepine sedative/anxiolytic drugs produce memory deficits similar to those observed in organic amnesia and may be useful tools for studying normal and abnormal memory mechanisms. The present double-blind, placebo-controlled repeated measures study examined the acute effects of orally administered triazolam (Halcion; 0.125 and 0.25 mg/70 kg), a benzodiazepine hypnotic, on performance in the Deese (1959)/Roediger-McDermott (1995) false recognition paradigm in 24 healthy volunteers. Paralleling previous demonstrations in amnesic patients, triazolam produced significant dose-related reductions in false recognition rates to nonstudied words associatively related to studied words, suggesting that false recognition relies on normal memory mechanisms impaired in benzodiazepine-induced amnesia. The results also suggested that relative to placebo, triazolam reduced participants' reliance on memory for item-specific versus list-common semantic information and reduced participants' use of remember versus know responses.     

Direct versus Indirect Well-Being Measures: Using Partially Structured Stimuli to Evaluate Well-Being

Given the important limitations of direct (explicit) measures, the study of indirect (implicit) measures of psychological constructs has received increased attention of social researchers. However, in the field of well-being the measures that have traditionally been used have tried to capture people’s well-being in an explicit and direct way, with some exceptions that are based mainly on adaptations of the Implicit Association Test (IAT). Given the critics that the IAT has received, the first aim of the present research was to develop a new life satisfaction measure using partially structured stimuli (PSWBS). The second goal was to examine the relation between direct and indirect well-being measures. In the first study, PSWBS showed good internal consistency, test–retest reliability and construct validity. Factorial analyses indicated that this measure acted as an indirect measure. In addition, direct and indirect well-being showed a significant but weak relation. To explain this result, in a second study we analyzed the moderating role of social comparison orientation on the relation between direct and indirect well-being measures. As expected, more social comparison tendency implied a stronger relation. In a third study we analyzed the criterion validity of both kind of measures. The PSWBS, the Personal Wellbeing Index-Adults and the Satisfaction With Life Scale significantly correlated with a criterion validity coefficient in terms of a semi-structured interview made by an external experimenter. Finally, in a fourth experiment we analyzed the influence of social desirability on direct and indirect measures of well-being. In contexts of high desirability, partially structured stimuli seemed to be more resistant to response factors (e.g., control of impressions) than traditional direct measures.

Retracted: Unconscious arithmetic processing: A direct replication

Across two experiments involving four conditions, Sklar et al. (2012) found that complex subtraction equations can be solved without awareness of the equations. These findings challenge the current position that consciousness is necessary for performing abstract, rule‐following tasks. Given the important implications of their work, we directly replicate Sklar's findings using a larger sample (n = 94) from a different population. Using Continuous Flash Suppression, we investigated if people were able to solve an equation after subliminal (1300 ms) exposure to it. We found evidence for unconscious addition but not subtraction. The effect of unconscious addition was eliminated when participants reported subjective awareness of the primes. Critical review of our results and implications for further research are discussed.
