Exaggeration in memory: Systematic distortion of self-evaluative information under reduced accessibility

The tendency to exaggerate specific information about oneself can stem from reconstructive memory processes that are distinct from motivated self-enhancement or self-presentation. While exaggerations sometimes reflect these motives, they also result from attempts to reconstruct one’s past. Three studies examined test scores as they became less accessible in memory. Study 1 provided a real-world illustration, demonstrating reduced accessibility and increased exaggeration of SAT scores over time. Two experiments utilized test scores randomly assigned in a controlled laboratory setting. Increased exaggeration was observed following distraction (Study 2), and after a one-week delay (Study 3). Distortions in scores reported were consistent with beliefs about the self, rather than uniformly self-serving. Under reduced accessibility, exaggeration was predicted by beliefs about achievement (Study 1) and subjective perceptions of test performance (Study 2). Study 3 manipulated perceived performance. Positive performance feedback caused greater exaggeration under reduced accessibility, whereas negative feedback reduced the tendency to exaggerate.     

A two-dimensional model that employs explicit and implicit attitudes to characterize prejudice

In the authors' 2-dimensional model of prejudice, explicit and implicit attitudes are used to create 4 profiles: truly low prejudiced (TLP: double lows), aversive racists (AR: low explicit modern racism/high implicit prejudice), principled conservatives (PC: high explicit modern racism/low implicit prejudice), and modern racists (MR: double highs). Students completed an Asian Modern Racism Scale and an Asian/White Implicit Association Test. The authors compared the 4 groups' prejudice-related ideologies (i.e., egalitarianism/humanism and social conservatism) and economic/political conservatism (Study 1, N=132). The authors also tested whether MR but not PC (Study 2, N=65) and AR but not TLP (Study 3, N=143) are more likely to negatively evaluate an Asian target when attributional ambiguity is high (vs. low). In support of the model, TLP did not hold prejudice-related ideologies and did not discriminate; AR were low in conservatism and demonstrated the attributional-ambiguity effect; PC did not strongly endorse prejudice-related ideologies and did not discriminate; MR strongly endorsed prejudice-related ideologies, were conservative, and demonstrated the attributional-ambiguity effect. The authors discuss implications for operationalizing and understanding the nature of prejudice.     

Better than average: alternatives to statistical summary representations for rapid judgments of average size

People can perceive the individual features of an object by focusing attention on it and binding the features together at a location. Some perceptual processing can occur without focusing attention on each object, though; people may even be able to extract summary information about the sizes of all the objects in a display, essentially computing the mean size at a glance. Evidence that people can judge the mean size of an array efficiently and accurately has been used to support the strong claim that people use a global, parallel process to extract a statistical summary of the average size of the objects in the display. Such claims are based both on the accuracy of performance and on the supposition that performance exceeds what would be possible with serial, focused attention. However, these studies typically have not examined the limits of performance with focused-attention strategies. Through experiments and simulations, we show that existing evidence for mean size perception can be explained through various focused-attention strategies, without appealing to a new mechanism of average size perception. Although our evidence does not eliminate the possibility that people do perceive the average size of all the objects in a display, it suggests that simpler mechanisms can accommodate the existing data.     

The link between emotional competence and well-being: a longitudinal study

What aspects of emotional competence help protect people from stress, anxiety, and depression, and help to promote positive affect? A total of 163 university students completed a two wave study that involved measuring emotional competence and emotional well-being at 1-year intervals. As expected, Time 1 measures of emotional competence predicted Time 2 measures of well-being, after controlling for Time 1 measures of well-being. Specifically, ineffective problem orientation predicted increases in anxiety and stress, and decreases in positive affect. Difficulty identifying and describing emotions predicted increases in anxiety and decreases in positive affect. Finally, an aspect of difficulty managing emotions (i.e. rumination) predicted decreases in positive affect. Each emotional competence variable predicted unique variance after controlling for other significant variables. We discuss the implications of these findings for counselling practice.     

Action information from classification learning

University of Illinois at Urbana-Champaign, Urbana, Illinois Much of our learning comes from interacting with objects. Two experiments investigated whether or not arbitrary actions used during category learning with objects might be incorporated into object representations and influence later recognition judgments. In a virtual-reality chamber, participants used distinct arm movements to make different classification responses. During a recognition test phase, these same objects required arm movements that were consistent or inconsistent with the classification movement. In both experiments, consistent movements were facilitated relative to inconsistent movements, suggesting that arbitrary action information is incorporated into the representations.     

Current status of the motor program: Revisited

The motor program is a concept that has had a major influence on theorizing in the field of motor control. However, there has been a lack of consensus as to what exactly is a motor program and its role in movement organization and execution. In 1994 Morris, Summers, Matyas, and Iansek concluded from a review of the application of the motor program concept in the field of physical therapy that continued use of the term may impede progress in the field. In this paper we examine what has happened to the motor program concept in the thirteen years since the previous evaluation. The review indicates that although the term is still being used in different ways, the theoretical existence of a motor program appears to be generally accepted by researchers in experimental psychology, movement science, and neurophysiology. The recent development of powerful brain imaging techniques may allow determination of whether the motor program should be regarded as a metaphorical or literal concept.     

The effect of trial-to-trial feedback on the error-related negativity and its relationship with anxiety

Individuals with anxiety disorders and related personality traits are characterized by increased error-related brain activity, as measured by the error-related negativity (ERN) in simple speeded response tasks. An absent, or opposite, relation between anxiety and the ERN has been reported in studies that employed reinforcement learning paradigms with trial-to-trial feedback. Understanding the effect of trial-to-trial feedback on the ERN may help clarify these results and can further elucidate the impact of feedback on performance monitoring. In the present study, 30 undergraduate participants performed two versions of the arrowhead version of the flanker task in counterbalanced order: one with trial-to-trial feedback and one without. The participants were slower and more accurate in the task with trial-to-trial feedback; however, the ERN was equivalent between the two tasks. Larger ERNs were related to higher trait anxiety, but only in the version without trial-to-trial feedback. These findings show that although trial-to-trial performance feedback impacts behavioral measures, it does not affect the ERN; moreover, the presence of trial-to-trial feedback moderates the relationship between the ERN and anxiety.     

The importance of information localization in scene gist recognition

People can recognize the meaning or gist of a scene from a single glance, and a few recent studies have begun to examine the sorts of information that contribute to scene gist recognition. The authors of the present study used visual masking coupled with image manipulations (randomizing phase while maintaining the Fourier amplitude spectrum; random image structure evolution [RISE]; J. Sadr & P. Sinha, 2004) to explore whether and when unlocalized Fourier amplitude information contributes to gist perception. In 4 experiments, the authors found that differences between scene categories in the Fourier amplitude spectrum are insufficient for gist recognition or gist masking. Whereas the global 1/f spatial frequency amplitude spectra of scenes plays a role in gist masking, local phase information is necessary for gist recognition and for the strongest gist masking. Moreover, the ability to recognize the gist of a target image was influenced by mask recognizability, suggesting that conceptual masking occurs even at the earliest stages of scene processing.
