Feedback specificity, exploration, and learning

Greater feedback specificity is generally considered to be beneficial for performance and learning, but the evidence for this generalization is limited. The authors argue that increasing the specificity of feedback is beneficial for initial performance but discourages exploration and undermines the learning needed for later, more independent performance. The results of their transfer experiment demonstrate that increasing the specificity of feedback positively affected practice performance, but its benefits did not endure over time or modification of the task. In addition, feedback specificity negatively affected levels of exploration during practice and interacted with exploration strategies to affect learning. The results suggest that those who received feedback of varying specificity may have learned through different but equally beneficial mechanisms.     

The positive and negative effects of anger on dispute resolution: evidence from electronically mediated disputes

Scholars have argued that anger expressed by participants in mediation is counterproductive; yet, there is also reason to believe that expressions of anger can be productive. The authors tested these competing theories of emotion by using data from online mediation. Results show that expression of anger lowers the resolution rate in mediation and that this effect occurs in part because expressing anger generates an angry response by the other party. However, when respondents are especially vulnerable, expressions of anger by the filer do not hinder settlement. The authors also examined precursors to anger, such as value of dispute and reputation, and the degree to which a focus on dispute resolution is reciprocated.     

An analysis of initial acquisition and maintenance of sight words following picture matching and copy cover, and compare teaching methods

This study compared the copy, cover, and compare method to a picture-word matching method for teaching sight word recognition. Participants were 5 kindergarten students with less than preprimer sight word vocabularies who were enrolled in a public school in the Pacific Northwest. A multielement design was used to evaluate the effects of the two interventions. Outcomes suggested that sight words taught using the copy, cover, and compare method resulted in better maintenance of word recognition when compared to the picture-matching intervention. Benefits to students and the practicality of employing the word-level teaching methods are discussed.     

A comparison of the MCMI-III personality disorder and modifier indices with the MMPI-2 clinical and validity scales

In this study, we examined the relationship of the MCMI-III (Millon, Davis, & Millon, 1997; Millon, Millon, & Davis, 1994) modifier indices and personality disorder scales to the validity and basic clinical scales of the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). The MCMI-III modifier indices highly correlated with all of the MMPI-2 validity scales except for the F(p) scale. Similarly, the MCMI-III personality disorder scales strongly covaried with the MMPI-2 validity and clinical scales except for the F(p) and 5 (Mf) scales. A factor analysis with Promax rotation revealed substantial relationships between the MMPI-2 and MCMI-III. However, the MMPI-2 F(p) scale did not tend to correlate with MMPI-2 or MCMI-III scales, indicating that F(p) scale variance was largely independent of other scales. The results suggest that clinicians should consider the interrelationship between personality characteristics and dissimulation.     

Rated importance of personal qualities across four relationships

Are there stable personal qualities that people value in others across a range of personal and professional relationships? For 4 relationship types that varied across social and professional associations (those of "close friend," "romantic partner," "an employee of yours," and "your boss"), participants rated each of 34 personal qualities on the basis of how important it would be in selecting someone for the relationship. The author factor-analyzed the ratings of importance and created composite scores to represent the 4 factors identified (intimacy, dependability, achievement, and kindness). The author found no difference that was due to relationship type for the factor of kindness. The relationship of romantic partners received the highest ratings on the factor of intimacy. Participants rated the relationship of close friends lower than the other 3 relationships for both of the factors of dependability and achievement. The results indicated that people value some qualities the same regardless of the relationship involved, with other qualities varying in importance across these relationships. Of special interest was the tendency of participants to see stable qualities as generally less important for choosing close friends than for choosing the others in the other three relationships.     

Estimates of emotional and psychometric intelligence: evidence for gender-based stereotypes

The authors examined participants' estimates of own and parental psychometric intelligence (IQ) and emotional intelligence (EI). The authors asked 224 participants (82 men, 138 women, 4 people who did not report their gender) to estimate their own and their parents' IQ and EI scores on a normal distribution ranging from 55 to 145 points. The authors hypothesized that men would give higher IQ but lower EI self-estimates than women and that participants, regardless of gender, would rate their fathers as higher on IQ but lower on EI than their mothers. The results confirmed the hypotheses, supporting the view that people perceive psychometric intelligence as a primarily masculine attribute in contrast with emotional intelligence, which they perceive as a primarily feminine attribute. The results also showed that the intensity of the stereotypical perception of EI as a feminine attribute diminished when the authors asked participants to estimate their scores on a range of specific EI facets instead of providing a direct overall self-estimate.     

An eye movement analysis of "mental rotation" of simple scenes

Participants saw a standard scene of three objects on a desktop and then judged whether a comparison scene was either the same, except for the viewpoint of the scene, or different, when one or more of the objects either exchanged places or were rotated around their center. As in Nakatani, Pollatsek, and Johnson (2002), judgment times were longer when the rotation angles of the comparison scene increased, and the size of the rotation effect varied for different axes and was larger for same judgments than for different judgments. A second experiment, which included trials without the desktop, indicated that removing the desktop frame of reference mainly affected the y-axis rotation conditions (the axis going vertically through the desktop plane). In addition, eye movement analyses indicated that the process was far more than a simple analogue rotation of the standard scene. The total response latency was divided into three components: the initial eye movement latency, the first-pass time, and the second-pass time. The only indication of a rotation effect in the time to execute the first two components was for z-axis (plane of sight) rotations. Thus, for x- and y-axis rotations, rotation effects occurred only in the probability of there being a second pass and the time to execute it. The data are inconsistent either with an initial rotation of the memory representation of the standard scene to the orientation of the comparison scene or with a holistic alignment of the comparison scene prior to comparing it with the memory representation of the standard scene. Indeed, the eye movement analysis suggests that little of the increased response time for rotated comparison scenes is due to something like a time-consuming analogue process but is, instead, due to more comparisons on individual objects being made (possibly more double checking).     

Tactile selective attention and body posture: assessing the multisensory contributions of vision and proprioception

This study addressed the role of proprioceptive and visual cues to body posture during the deployment of tactile spatial attention. Participants made speeded elevation judgments (up vs. down) to vibrotactile targets presented to the finger or thumb of either hand, while attempting to ignore vibrotactile distractors presented to the opposite hand. The first two experiments established the validity of this paradigm and showed that congruency effects were stronger when the target hand was uncertain (Experiment 1) than when it was certain (Experiment 2). Varying the orientation of the hands revealed that these congruency effects were determined by the position of the target and distractor in external space, and not by the particular skin sites stimulated (Experiment 3). Congruency effects increased as the hands were brought closer together in the dark (Experiment 4), demonstrating the role of proprioceptive input in modulating tactile selective attention. This spatial modulation was also demonstrated when a mirror was used to alter the visually perceived separation between the hands (Experiment 5). These results suggest that tactile, spatially selective attention can operate according to an abstract spatial frame of reference, which is significantly modulated by multisensory contributions from both proprioception and vision.
