Auditory registration without learning

In 3 studies, the authors explore how repeated exposure to a spoken word affects memory for perceptual attributes associated with the word (such as a talker's voice or a word's plurality). Subjects heard a list of words; particular words were repeated differing numbers of times. At test, subjects estimated the frequency of each word, with instructions to give frequency judgments of "zero" to words with changed attributes. The experiments demonstrate that memory for perceptual attributes improves very little after the first few repetitions, although word memory continues to improve. The experiments extend the registration without learning effect (D. L. Hintzman, T. Curran, & B. Oppy, 1992) to auditory words, to complex attributes (voice), and to conditions of low and high stimulus variability (two or many voices).     

Anger and social appraisal: a "spicy" sex difference?

The central objective of this study was to investigate the role of social appraisal in sex differences in anger expression. Anger expression was inferred from the amount of hot sauce given to the person who induced anger. Participants were randomly assigned to a social condition, in which they expected to meet this person, or to a nonsocial condition, in which they had no such expectation. Men and women differed in their anger expressions, despite the fact that they did not differ in anger experience. Women expressed anger to a lesser extent than men, but only in the social condition. Social appraisal partly mediated the relation between sex and anger expression. The role of social appraisal in emotion and appraisal theory is discussed.     

Flank transparency: transparent filters seen in dynamic two-color displays

Flank transparency is the perception of a colored transparent filter evoked by apparent-motion displays containing as few as two colors. Displays of flank transparency contain a random array of line segments placed on a uniform background. Small flanks are added to the line segments if the segments fall in the interior of a moving virtual shape, such as a virtual disk. This leads to the perception of a colored transparent disk with well-defined boundaries moving over the array of lines. Current qualitative and quantitative models of luminance and color conditions for perceptual transparency do not account for flank transparency as they require displays containing at least three different colors.     

The role of honour concerns in emotional reactions to offences

We investigated the role of honour concerns in mediating the effect of nationality and gender on the reported intensity of anger and shame in reaction to insult vignettes. Spain, an honour culture, and The Netherlands, where honour is of less central significance, were selected for comparison. A total of 260 (125 Dutch, 135 Spanish) persons participated in the research. Participants completed a measure of honour concerns and answered questions about emotional reactions of anger and shame to vignettes depicting insults in which type of threat was manipulated. It was found that Spanish participants responded especially intensely to insults that threaten family honour, and that this effect of nationality on emotional reactions to threats to family honour was mediated by individual differences in concern for family honour.     

Visual extinction and awareness: The importance of binding dorsal and ventral pathways

Patients with visual extinction were tested on three tasks involving stimulus identification and localization. In the first experiment, in which patients were to identify and localize stimuli, they demonstrated high levels of contralesional omissions. This primarily occurred under conditions of double simultaneous stimulation (DSS), consistent with the character of extinction. In contrast, when patients had to simply localize or count stimuli in Experiment 2, their contralesional omissions were very low. Similarly, when patients were to identify stimuli without localizing them (Experiment 3) they again showed very low contralesional error rates. These results support the view (Baylis, Driver, & Rafal, 1993) that visual extinction may be greatest when information about location cannot be bound to information about identity.     

Toward establishing a qualifying autoclitic repertoire in children with autism spectrum disorder

Autoclitics are secondary verbal operants that are controlled by a feature of the conditions that occasion or evoke a primary verbal operant such as a tact or mand. Qualifying autoclitics extend, negate, or assert a speaker's primary verbal response and modify the intensity or direction of the listener's behavior. Howard and Rice (1988) established autoclitics that indicated weak stimulus control (e.g., “like a [primary tact]”) with four neurotypical preschool children. However, generalization to newly acquired tacts was limited. In Experiment 1, we addressed similar behavior as in Howard and Rice but with autistic children while using simultaneous teaching procedures, and we observed generalization across sets and with newly acquired tacts. In Experiment 2, we evaluated the effects of multiple-exemplar training on generalization of autoclitics across sets of naturalistic stimuli. Across participants, gradual increases in the frequency of autoclitics occurred with untaught stimuli after teaching with one or more sets.

Olfactory learning-induced enhancement of the predisposition for LTP induction

Learning of a particularly difficult olfactory-discrimination (OD) task results in acquisition of rule learning. This enhancement in learning capability is accompanied by the long-term enhancement of synaptic connectivity between piriform cortex pyramidal neurons. In this study we examined whether olfactory rule learning would modify the predisposition to induce long-term potentiation (LTP) in the pathway projecting from the piriform cortex to the olfactory bulb. We report that OD learning was associated with enhancement in the predisposition to induce LTP. This learning-related effect may be affected by process generation of new granule cells located in the olfactory bulb.     

An obscure rider obstructing science: the conflation of parthenotes with embryos in the Dickey-Wicker amendment

In 1996 Congress passed the Dickey-Wicker Amendment (DWA) as part of an appropriations bill; it has been renewed every year since. The DWA bans federal funding for research using embryos and parthenotes. In this paper, we call for a public discussion on parthenote research and a questioning of its inclusion in the DWA. We begin by explaining what parthenotes are and why they are useful for research on reproduction, cancer, and stem cells. We then argue that the scientific difference between embryos and parthenotes translates into ethical differences, and claim that research on parthenotes is much less ethically problematic. Finally, we contextualize the original passage of the DWA to provide an explanation for why the two were possibly conflated in this law. We conclude by calling for a public discussion on reconsidering the DWA in its entirety, starting with the removal of parthenogenesis from this prohibition of National Institutes of Health (NIH) funding.     

The Development and Evaluation of a Parent Empowerment Program for Family Peer Advocates

Family-to-family services are emerging as an important adjunctive service to traditional mental health care and a vehicle for improving parent engagement and service use in children’s mental health services. In New York State, a growing workforce of Family Peer Advocates (FPA) is delivering family-to-family services. We describe the development and evaluation of a professional program to enhance Family Peer Advocate professional skills, called the Parent Engagement and Empowerment Program (PEP). We detail the history and content of PEP and provide data from a pre/post and 6-month follow up evaluation of 58 FPA who participated in the first Statewide regional training effort. Self-efficacy, empowerment, and skills development were assessed at 3 time points: baseline, post-training, and 6-month follow-up. The largest changes were in self-efficacy and empowerment. Regional differences suggest differences in Family Peer Advocate workforce across areas of the state. This evaluation also provides the first systematic documentation of Family Peer Advocate activities over a six-month period. Consistent with peer specialists within the adult health care field, FPA in the children’s mental health field primarily focused on providing emotional support and service access issues. Implications for expanding family-to-family services and integrating it more broadly into provider organizations are described.
