Rats' sensitivity to their direction of movement and spontaneous alternation behaviour

The response of rats to their prior direction of movement was examined in three spontaneous alternation experiments. In the first, a straight alley run interpolated between two T-maze trials increased goal arm alternation when it was in the same direction as that of the animal's first T-maze goal arm entry and decreased the alternation tendency when it was in the opposite direction. Experiment II found that multiple runs in one direction in a straight alley increased the likelihood that rats would subsequently enter the goal arm of a T-maze which permitted movement in an opposite direction. In the third experiment, rats entered those goal arms of an eight-arm radial maze which permitted movement in any direction which was different from that during a preceding straight alley trial. The results of these experiments indicate that rats are quite sensitive to their direction of movement and use it as a cue in guiding their behaviour in a variety of experimental situations.     

Two investigations of “female modesty” in achievement situations

Two experiments examined motivations underlying the common finding that females present themselves more modestly than males in achievement situations. In Study 1, 388 first-year college students, primarily European-Americans, predicted their first semester grade point averages (GPAs) in one of 3 public and 2 private conditions, which varied the salience of modesty concerns and/or concerns about the others' feelings. In the public conditions combined, but not in the private conditions, women's predictions were lower than men's, although there were no gender differences in actual GPA. The public condition in which the others' feelings and modesty concerns were made salient accounted for this difference between men and women. In Study 2, 230 first-year college students predicted their first-semester GPAs in private, in public to a “nonvulnerable” other, or in public to a “vulnerable” other (someone who supposedly had earned a low GPA). Women's estimates were lower than men's in the latter condition only and lower than their estimates in the other conditions. These results suggest that relational motivations, rather than a simple lack of self-confidence or modesty alone, are a factor in gender differences in self-presentation of achievement.     

Retracted: When nothing compares to me: how defensive motivations and similarity shape social comparison effects

While similarity typically breeds social comparison, all information gained from social comparisons is not equally influential. Three studies illustrate the situations in which individuals defensively interpret social comparison information such that they incorporate information that reflects positively on the self and disregard negative information. Study 1 extends previous research to show that self‐threat broadens the conditions under which defensive interpretations occur to include those in which similarity is ambiguous. Studies 2 and 3 demonstrate that defensive interpretations are less likely to occur when individuals are affirmed or when the comparison information is unimportant. These findings suggest that the impact of social comparisons on self‐views is determined by both similarity of comparison targets and the motives of the perceiver.

The Effect of Response Cards on Participation and Weekly Quiz Scores of University Students Enrolled in Introductory Psychology Courses

Increasing student participation in college classrooms is an overlooked yet socially valid endeavor. The present study attempted to increase student participation, accuracy of responding, and weekly quiz scores, by incorporating student response-cards. Measures of social validity were also addressed. One hundred twenty university students in two sections of an introductory course served as participants. An augmented incomplete ABA reversal design was used to compare the effects of review questions with and without response-cards. Results suggest that response cards can increase participation as well as measures of learning, in this case quiz scores. Also, students rated the intervention positively on a consumer satisfaction rating scale. In addition to improving rates of student participation and quiz scores, response-cards positively impacted both students and the instructor's subjective experience in the classroom.     

Expectations,gains, and losses in the anterior cingulate cortex

The anterior cingulate cortex (ACC) participates in evaluating actions and outcomes. Little is known on how action-reward values are processed in ACC and if the context in which actions are performed influences this processing. In the present article, we report ACC unit activity of monkeys performing two tasks. The first task tested whether the encoding of reward values is context dependent—that is, dependent on the size of the other rewards that are available in the current block of trials. The second task tested whether unexpected events signaling a change in reward are represented. We show that the context created by a block design (i.e., the context of possible alternative rewards) influences the encoding of reward values, even if no decision or choice is required. ACC activity encodes the relative and not absolute expected reward values. Moreover, cingulate activity signals and evaluates when reward expectations are violated by unexpected stimuli, indicating reward gains or losses.     

Prediction,Authority, and Entitlement in Shared Activity

Shared activity is often simply willed into existence by individuals. This poses a problem. Philosophical reflection suggests that shared activity involves a distinctive, interlocking structure of intentions. But it is not obvious how one can form the intention necessary for shared activity without settling what fellow participants will do and thereby compromising their agency and autonomy. One response to this problem suggests that an individual can have the requisite intention if she makes the appropriate predictions about fellow participants. I argue that implementing this predictive strategy risks derailing practical reasoning and preventing one from forming the intention. My alternative proposal for reconciling shared activity with autonomy appeals to the idea of acting directly on another's intention. In particular, I appeal to the entitlement one sometimes has to another's practical judgment, and the corresponding authority the other sometimes has to settle what one is to do.     

Desire for control,perception of control: their impact on autonomous motivation and psychological adjustment

The purpose of the present research was to test the relevance of a theoretical framework based on the matches and the mismatches between desire for control and perception of control (Evans et al. in Br J Psychol 84(2):255–273, 1993), in order to predict autonomous motivation (Deci and Ryan in Intrinsic motivation and self-determination in human behavior. Plenum, New York, 1985, 2012), depression, and anxiety (Bradley in Handbook of psychology and diabetes: A guide to psychological measurement in diabetes research and practice. Harwood Academic Press, Chur, 1994; Bruchon-Schweitzer in Psychologie de la Santé: Modèles, concepts et méthodes. Dunod, Paris, 2002). Two prospective studies were run among undergraduate students. Results of Study 1 confirmed the relevance of Evans et al.’s (in Br J Psychol 84(2):255–273, 1993) theoretical framework. More specifically, four clusters reflecting different levels of desire for control and perception of control were found. Moreover, results revealed that profiles characterized by high scores on both desire for control and perception of control were more autonomously motivated than those characterized by the three other possible combinations. Results of Study 2 replicated those of Study 1 and showed that participants combining a low desire for control and a high perception of control were the less depressed, followed by participants with high scores on both measures. No significant effects were found for anxiety.     

Reducing the Misinformation Effect Through Initial Testing: Take Two Tests and Recall Me in the Morning?

Initial retrieval of an event can reduce people's susceptibility to misinformation. We explored whether protective effects of initial testing could be obtained on final free recall and source‐monitoring tests. After studying six household scenes (e.g., a bathroom), participants attempted to recall items from the scenes zero, one, or two times. Immediately or after a 48‐hour delay, non‐presented items (e.g., soap and toothbrush) were exposed zero, one, or four times through a social contagion manipulation in which participants reviewed sets of recall tests ostensibly provided by other participants. A protective effect of testing emerged on a final free recall test following the delay and on a final source‐memory test regardless of delay. Taking two initial tests did not increase these protective effects. Determining whether initial testing will have protective (versus harmful) effects on memory has important practical implications for interviewing eyewitnesses. © 2015 The Authors.
