Combating stereotype threat: The effect of self-affirmation on women’s intellectual performance

The present studies were designed to investigate the effects of self-affirmation on the performance of women under stereotype threat. In Study 1, women performed worse on a difficult math test when it was described as diagnostic of math intelligence (stereotype threat condition) than in a non-diagnostic control condition. However, when women under stereotype threat affirmed a valued attribute, they performed at levels comparable to men and to women in the no-threat control condition. In Study 2, men and women worked on a spatial rotation test and were told that women were stereotyped as inferior on such tasks. Approximately half the women and men self-affirmed before beginning the test. Self-affirmation improved the performance of women under threat, but did not affect men’s performance.     

Introducing Science to the Psychology of the Soul: Experimental Existential Psychology

ABSTRACT— Humans live out their lives knowing that their own death is inevitable; that their most cherished beliefs and values, and even their own identities, are uncertain; that they face a bewildering array of choices; and that their private subjective experiences can never be shared with another human being. This knowledge creates five major existential concerns: death, isolation, identity, freedom, and meaning. The role of these concerns in human affairs has traditionally been the purview of philosophy. However, recent methodological and conceptual advances have led to the emergence of an experimental existential psychology directed toward empirically investigating the roles that these concerns play in psychological functioning. This new domain of psychological science has revealed the pervasive influence of deep existential concerns on diverse aspects of human thought and behavior.

Using Brief Experimental Analysis to Select Oral Reading Interventions: An Investigation of Treatment Utility

This study examined the treatment utility of brief experimental analysis for selecting skill-based oral reading interventions that targeted acquisition and fluency. Two second and one third grade student served as participants. The potentially most and least effective instructional packages identified from the brief experimental analysis for each student were alternated during an extended analysis phase. The instructional components that were compared were based on an ease of implementation hierarchy, with the brief experimental analysis used to select the hypothesized most effective instructional package for oral reading. Visual analysis of extended analysis data revealed that the hypothesized most effective combination of instructional components identified from the brief analysis produced greater initial gains in reading for two children (i.e., over 29 and 21 intervention days) and greater gains in reading throughout the extended analysis phase for the third child. Thus, the investigation provided preliminary evidence for the treatment utility of using brief experimental analysis to select effective and efficient oral reading instructional interventions. Implications, limitations, and future research topics are discussed.     

Residual costs in task switching: testing the failure-to-engage hypothesis

Reaction time is typically longer on trials on which the task changes. Thisswitch cost is reduced by the opportunity to prepare for the change before the stimulus onset, but there remains aresidual cost that resists reduction by further opportunity for preparation. De Jong (2000) proposed a model for evaluating the contribution to the residual cost of (1) failure to achieve endogenous task-set reconfiguration on a proportion of trials, and (2) limitations to the completeness of reconfiguration attainable by endogenous means. We report good fits of the model to the data from one previous and one new task-switching experiment, suggesting that the residual switch cost may indeed be attributable to a probabilistic failure to complete advance preparation. But strong incentives for preparation only marginally increased the estimated preparation probability, suggesting some intrinsic limitation to the ability to achieve endogenous preparation for a task switch on every trial.     

Sensitivity of children's behavior to probabilistic reward: effects of a decreasing-ratio lottery system on math performance

Probabilistic reward has been shown to affect children's choice behavior in game-like activities. We examined the effects of a lottery system containing progressively lower exchange ratios on children's completion of math problems. Two of the 3 children completed problems above baseline levels until the chance of exchange dropped to 25%. This study describes a potentially useful method for examining reinforcement schedules in applied settings and extends previous research on probabilities of reinforcement.     

Measuring motivations for intercollegiate athlete alcohol use: a confirmatory factor analysis of the drinking motives measure

This study examined the psychometric properties of the Drinking Motives Measure (DMM) on a sample of 227 collegiate athletes. Confirmatory factor analyses indicated that the 4-factor structure of the DMM provided a better fit than either 2- or 1-factor models, but the overall fit of the 4-factor model was moderate at best. A revised 3-factor model consistent with prior research (M. L. Cooper, M. Russell, J. B. Skinner, & M. Windle, 1992) provided the best fit. Hierarchical multiple regression analyses indicated that the 3 DMM factors included in the revised model accounted for 17%-21% of the unique variance on alcohol consumption variables. Results provide preliminary evidence supporting the internal consistency, construct validity, and convergent validity of the revised 3-factor DMM with collegiate athletes.     

Psychological defense in anticipation of anxiety: eliminating the potential for anxiety eliminates the effect of mortality salience on worldview defense

A large body of research has shown that when people are reminded of their mortality, their defense of their cultural worldview intensifies. Although some psychological defenses seem to be instigated by negative affective responses to threat, mortality salience does not appear to arouse such affect. Terror management theory posits that the potential to experience anxiety, rather than the actual experience of anxiety, underlies these effects of mortality salience. If this is correct, then mortality-salience effects should be reduced when participants believe they are not capable of reacting to the reminder of mortality with anxiety. In a test of this hypothesis, participants consumed a placebo purported to either block anxiety or enhance memory. Then we manipulated mortality salience, and participants evaluated pro- and anti-American essays as a measure of worldview defense. Although mortality salience intensified worldview defense in the memory-enhancer condition, this effect was completely eliminated in the anxiety-blocker condition. The results suggest that some psychological defenses serve to avert the experience of anxiety rather than to ameliorate actually experienced anxiety.     

Being prepared on time: on the importance of the previous foreperiod to current preparation, as reflected in speed, force and preparation-related brain potentials

How do participants adapt to temporal variation of preparatory foreperiods? For reaction times, specific sequential effects have been observed. Responses become slower when the foreperiod is shorter on the current than on the previous trial. If this effect is due to changes in motor activation, it should also be visible in force of responses and in EEG measures of motor preparation, the contingent negative variation (CNV) and the lateralized readiness potential (LRP). These hypotheses were tested in a two-choice reaction task, with targets occurring 500, 1500, or 2500 ms after an acoustic warning signal. The reaction time results showed the expected pattern and were accompanied by similar effects on a fronto-central CNV and the LRP. In contrast, the increase of response force with brief current foreperiods did not depend on previous foreperiods. Thus, EEG measures confirm that sequential effects on RT are at least partially due to changes in motor activation originating from previous trials. Effects found on response force may be related to general response readiness rather than activation of motor-hand areas, which may explain the absence of a sequential effect on force in the current experiment.     

Effects of task difficulty and type of contingency on students' allocation of responding to math worksheets

This study investigated students' allocation of responding as a function of task difficulty and type of reinforcement contingency (i.e., accuracy based or time based). Four regular education fourth-grade students were presented with two identical stacks of easy and then difficult math worksheets using a reversal design. Regardless of condition, completing problems from each stack of worksheets was reinforced according to a different contingency; one required correct completion of math problems (accuracy based) and one required on-task behavior (time based). Results suggested that 3 of the 4 students preferred the accuracy-based contingency when given easy material and the time-based contingency when given difficult material. One student allocated more responding to the accuracy-based contingency when given easy problems but did not show a clear preference for either contingency with difficult problems. The implications of these findings for designing reinforcement-based programs for tasks of varying difficulty are discussed.
