Commission errors but not critical lures decrease when you have to pay a price for them

Using the Deese-Roediger-McDermott paradigm, we explored the effect of monetary penalty on false memories. Participants were presented 6 15-word lists of semantic associates that all converged on a nonpresented critical lure. Next, half of the participants received a monetary reward (0.10 Euro; about $0.10) for each correctly recalled word, whereas they lost money (0.20 Euro; about $0.20) for each incorrect response. Compared with control participants who received a fixed financial compensation, participants in the experimental group reported fewer commissions (i.e., incorrect responses other than the critical lure). Number of hits and critical lures did not differ between the groups.     

What can subjective forgetting tell us about memory for childhood trauma?

In the present study, we examined the prevalence and predictors of subjective forgetting (i.e., self-reported amnesia) of child sexual abuse (CSA). Adults who, as children, were involved as victims in legal prosecutions were questioned about their CSA experiences, which had been documented in the 1980s, and about lost and recovered memory of those experiences. Males and individuals who experienced more severe abuse were more likely to report forgetting. The majority of individuals attributed their forgetting to active attempts to avoid thinking about the abuse. In contrast, when predictors of subjective forgetting were used to predict objective memory of abuse, more severe abuse and more extended legal involvement were associated with fewer memory errors. The differences between subjective and objective memory underscore the risks of using subjective measures to assess lost memory of abuse.     

Reaching with alien limbs: visual exposure to prosthetic hands in a mirror biases proprioception without accompanying illusions of ownership

In five experiments, we investigated the effects of visual exposure to a real hand, arubber hand, or a wooden block on reaching movements made with the unseen left hand behind a parasagittal mirror. Participants reached from one of four starting positions, corresponding to four levels of conflict between the proprioceptively and visually specified positions of the reaching hand. Reaching movements were affected most by exposure to the real hand, intermediately by the rubber hand, and least of all by the wooden block When the posture and/or movement of the visible hand was incompatible with that of the reaching hand, the effect on reaching was reduced. A "rubber hand illusion" questionnaire revealed that illusions of ownership of the rubber hand were not strongly correlated with reaching performance. This research suggests that proprioception is recalibrated following visual exposure to prosthetic hands and that this recalibration is independent of the rubber hand illusion.     

Spouses' attributions for helping: the effects of styles of help-seeking,self-serving bias,and sex

This paper examines the effects of (a) how clearly the desire for help is presented, (b) self-serving bias, and (c) sex differences on the source of the cause of helping happening (or not) that spouses attribute to a potential helper. In two studies, a total of 138 couples imagined situations in which a person wanted his or her spouse to do a chore. How clearly the desire for help was expressed, whether help was given, and whether it was the participant or the spouse who was expected to help were manipulated. The participants reported their attributions for the cause of helping (or not) to themselves and the spouse on visual analog scales. There was strong support for a proposed interaction between how clearly the desire for help was expressed and whether help was given in predicting spouses' attributions. No support was obtained for a predicted self-serving bias or for a suggestion that men make more self-enhancing attributions than women, the findings were instead congruent with a relationship-enhancing bias. The findings are discussed in terms of the context of housework.

Viewing oneself during synchronous online learning increases appearance anxiety and decreases memory for lecture content

In response to the COVID-19 pandemic, instructors began using online learning platforms to offer live remote instruction (e.g., Zoom), which allow students to view themselves in real-time (i.e., self-view). The present research examined whether having students keep their cameras on, relative to cameras off, during a live online lecture would increase anxiety and reduce learning. In both Experiment 1a (small group setting) and Experiment 1b (large group setting), students in the camera-on condition did not report greater state anxiety, nor was anxiety associated with lower performance on an immediate multiple-choice exam. Experiment 2 specifically examined the effect of self-view and if appearance anxiety (rather than state anxiety) might mediate the relationship between camera use and test performance. Results indicate that participants viewing themselves reported significantly higher appearance anxiety, and that higher appearance anxiety was related to decreased learning. These findings suggest that viewing oneself may uniquely contribute to heightened appearance anxiety and may reduce memory for content when learning synchronously online.     

Individual differences in white matter microstructure predict semantic control

In everyday conversation, we make many rapid choices between competing concepts and words in order to convey our intent. This process is termed semantic control, and it is thought to rely on information transmission between a distributed semantic store in the temporal lobes and a more discrete region, optimized for retrieval and selection, in the left inferior frontal gyrus. Here, we used diffusion tensor imaging in a group of neurologically normal young adults to investigate the relationship between semantic control and white matter tracts that have been implicated in semantic memory retrieval. Participants completed a verb generation task that taps semantic control (Snyder & Munakata, 2008; Snyder et al., 2010) and underwent a diffusion imaging scan. Deterministic tractography was performed to compute indices representing the microstructural properties of the inferior fronto-occipital fasciculus (IFOF), the uncinate fasciculus (UF), and the inferior longitudinal fasciculus (ILF). Microstructural measures of the UF failed to predict semantic control performance. However, there was a significant relationship between microstructure of the left IFOF and ILF and individual differences in semantic control. Our findings support the view put forth by Duffau (2013) that the IFOF is a key structural pathway in semantic retrieval.     

DIAGNOSTIC EXPLOITATION OF VISUAL AFTEREFFECT MEASURES IN A MODERATELY DEPRESSIVE PATIENT GROUP

SMITH, G. J. W., FRIES, I., ANDERSSON, A. L. & RIED, J. Diagnostic exploitation of visual aftereffect measures in a moderately depressive patient group. Scand. J. Psychol. , 1971, 12, 68–79.–A group of 39 moderately depressive patients were tested before and after therapy with two serial aftereffect tests. One of them concerned size, intensity, and color of projected afterimages (AI), the other the duration of spiral aftereffects (SAE). AI and SAE data correlated highly with psychiatric ratings of depressive retardation, anxiety, and compulsion. These correlations formed the nucleus of three independent dimensions in a factorial space.
