"False recall of critical lures in students with diagnosed learning disabilities": a historical correction and a brief commentary

Referring to a popular procedure for examining false recall, in 2007 Branch, et al. stated that its two acronyms ("DRM" and "DRMRS") reflected variations in the procedure at the time of testing. However, the acronyms primarily reflect variations in the people to whom the basic procedure should be attributed. A calculation error in their paper is also corrected, and it is observed that magnitudes of both false recall and correct recall obtained by their young adolescents with no learning difficulties are similar to those with adults. Theoretical implications are discussed.     

Integrating haptic-tactile feedback into a video-capture-based virtual environment for rehabilitation.

Video-capture virtual reality (VR) systems are gaining popularity as intervention tools. To date, these platforms offer visual and audio feedback but do not provide haptic feedback. We contend that adding haptic feedback may enhance the quality of intervention for various theoretical and empirical reasons. This study aims to integrate haptic-tactile feedback into a video capture system (GX VR), which is currently applied for rehabilitation. The proposed multi-modal system can deliver audio-visual as well as vibrotactile feedback. The latter is provided via small vibratory discs attached to the patient's limbs. This paper describes the system, the guidelines of its design, and the ongoing usability study.     

Conformity in a generative linguistic task: the role of category and strategic nonword use.

Marsh, Ward, and Landau (1999) demonstrated that participants asked to create novel words use elements of sample nonwords they are given, even when instructed to avoid use of the examples. In four studies, we replicated the effect of conformity to sample nonwords and found the effect was not influenced by the semantic category of the words unless those words shared orthographic characteristics. We found that although we could increase conformity to examples when word exemplars were grouped by category, it was likely that much of this increase was strategically driven. We propose that the presence of the sample non-words, presented in groups with the same word rules, created an orthographic category used by participants in the word creation task.     

An analysis of coordinated responding of pigeons

Experimental analyses of coordinated responding (i.e., cooperation) have been derived from a procedure described by Skinner (1962) in which reinforcers were delivered to a pair of subjects (a dyad) if both responded within a short interval, thus satisfying a coordination contingency. Although it has been suggested that this contingency enhances rates of temporally coordinated responding, limitations of past experiments have raised questions concerning this conclusion. The present experiments addressed some of these limitations by holding the schedule of reinforcement (Experiment 1: fixed ratio 1; Experiment 2; variable interval 20 s) constant across phases and between dyad members and by varying, in different conditions, the number of response keys (one to three) across which coordination could occur. Greater percentages of coordinated responding occurred under the coordinated-reinforcement phases than under independent-reinforcement phases in most conditions. The one exception during the one-key condition of Experiment 1 appeared to be a consequence of variability introduced by the independent-reinforcement phase procedure. Furthermore, coordination percentages decreased with increasing response options under both schedules. These results confirm and extend the finding that coordination contingencies control higher rates of temporally coordinated responding than independent-reinforcement contingencies do.     

Sexual activity is inversely related to women’s perceptions of the facial attractiveness of unknown men

A study was conducted to assess whether individual differences in sexual activity during the past 30 days, in particular penile–vaginal intercourse (PVI; which is associated with measures of relationship quality), are related to the perception of the facial attractiveness of unknown men. Forty-five women reported the frequency of a variety of sexual behaviors and rated the facial attractiveness and friendliness of 24 men. Women who reported more frequent orgasm from masturbation rated men as less friendly. This finding might be reflective of the more anti-social attitude associated with more frequent masturbation. The results also show that women who engaged more frequently in most kinds of sexual behavior, not only PVI, considered unknown men to be less facially attractive. That is, individuals who engage more frequently in a variety of sexual behaviors with their partner perceived unknown men as less attractive and thereby may be less susceptible to the lure of other (or if the only sexual behavior is masturbation, any) men.     

Verbal Sexual Coercion and Perceived Victim Responsibility: Mediating Effects of Perceived Control

Verbal coercion involves unwanted sexual penetration compelled by psychological pressure. It was hypothesized that, to the degree that verbal coercion is seen as controllable, victims may be held more responsible. Two samples of US undergraduates rated perceptions of hypothetical sexual coercion scenarios. In Study 1, participants (N = 120) read scenarios of either verbal coercion or rape by a male dating partner. Participants perceived verbal coercion as more controllable than rape, which accounted for the greater responsibility attributed to verbal coercion victims. In Study 2, participants (N = 275) read scenarios involving either male-to-female or female-to-male verbal coercion. Participants perceived female-to-male coercion as more controllable, which accounted for the greater responsibility attributed to a verbally coerced man.     

Children's emotion regulation: Self-report and physiological response to peer provocation

The authors examined the notion that children's emotion regulation (ER) is a uniform skill by (a) investigating the concordance between self-report of ER and physiological measures and by (b) examining ER in a specific context (e.g., peer provocation) and context-free manner (e.g., during a semistructured interview of ER abilities). Seventy-two children in middle childhood (average age = 9 years) participated. Time-locked measures of heart rate reactivity and recovery were obtained in response to provoking comments, and vagal regulation was measured throughout the provocation session. Children who reported greater dysregulation showed increased heart rate reactivity to provocative comments (i.e., steeper heart rate slope) but no difference in heart rate recovery. The context-free but not the context-specific self-report measure was associated with a failure to suppress vagal tone. Implications for ER measurement and children's peer relations are discussed.     

Fictions,feelings, and emotions

Many philosophers suggest (1) that our emotional engagement with fiction involves participation in a game of make-believe, and (2) that what distinguishes an emotional game from a dispassionate game is the fact that the former activity alone involves sensations of physiological and visceral disturbances caused by our participation in the game. In this paper I argue that philosophers who accept (1) should reject (2). I then illustrate how this conclusion illuminates various puzzles in aesthetics and the philosophy of mind.
