Empathy and generalized reciprocity in compliance with requests for help

This study examined empathy and reciprocity as explanations for why people comply with requests for help. Participants (35 male and 62 female) imagined being asked for money by a person who had locked keys in a car and then reported how likely they would he to comply with such a request, whether they had previously locked their keys in their car (empathy), and, if so, whether they had been helped (reciprocity). In support of the explanation based on empathy, people who reported previously locking their keys in their cars indicated being more likely to comply.     

Age differences in overlapping-task performance: evidence for efficient parallel processing in older adults

Two psychological refractory period (PRP) experiments were conducted to examine overlapping processing in younger and older adults. A shape discrimination task (triangle or rectangle) for Task 1 (T1) and a lexical-decision task (word or nonword) for Task 2 (T2) were used. PRP effects, response time for T2 increasing as stimulus onset synchrony (SOA) decreased, were obtained for both age groups. The effect of word frequency on T2 was smaller at the short SOA than at the long SOA, reflecting slack effects, which were larger for older than younger adults in both experiments. These results suggest that older adults can perform lexical access of T2 in parallel with the processing of T1 at least as efficiently as younger adults.     

Visual word recognition: reattending to the role of spatial attention

Three experiments examine whether spatial attention and visual word recognition processes operate independently or interactively in a spatially cued lexical-decision task. Participants responded to target strings that had been preceded first by a prime word at fixation and then by an abrupt onset cue either above or below fixation. Targets appeared either in the cued (i.e., valid) or uncued (i.e., invalid) location. The proportion of validly cued trials and the proportion of semantically related prime-target pairs were manipulated independently. It is concluded that spatial attention and visual word recognition processes are best seen as interactive. Spatial attention affects word recognition in 2 distinct ways: (a) it affects the uptake of orthographic information, possibly acting as "glue" to hold letters in their proper places in words, and (b) it (partly) determines whether or not activation from the semantic level feeds down to the lexical level during word recognition.     

Making syntax of sense: number agreement in sentence production

Grammatical agreement flags the parts of sentences that belong together regardless of whether the parts appear together. In English, the major agreement controller is the sentence subject, the major agreement targets are verbs and pronouns, and the major agreement category is number. The authors expand an account of number agreement whose tenets are that pronouns acquire number lexically, whereas verbs acquire it syntactically but with similar contributions from number meaning and from the number morphology of agreement controllers. These tenets were instantiated in a model using existing verb agreement data. The model was then fit to a new, more extensive set of verb data and tested with a parallel set of pronoun data. The theory was supported by the model's outcomes. The results have implications for the integration of words and structures, for the workings of agreement categories, and for the nature of the transition from thought to language.     

Using Methods That Matter: The Impact of Reflection,Dialogue, and Voice

In recent years, the field of community psychology has given considerable attention to how research and evaluation methods should be designed to support our goals of empowerment and social justice. Yet, as a field, we have given much less attention to whether the use of our methods actually achieves or supports our empowerment agenda. With the primary purpose of beginning to establish the norm of reporting on the impacts of our methods, this paper reports on the findings from interviews of 16 youth and adults who had participated in one participatory evaluation method (Photovoice). Two specific questions were examined: (1) What is the impact of participating in a Photovoice effort; and (2) How does the method of Photovoice foster these impacts? Overall, participants noted that they were significantly affected by their experiences as photographers and through their dialogue with neighbors during Photovoice group sessions. Impacts ranged from an increased sense of control over their own lives to the emergence of the kinds of awareness, relationships, and efficacy supportive of participants becoming community change agents. According to participants, Photovoice fostered these changes by (a) empowering them as experts on their lives and community, (b) fostering deep reflection, and (c) creating a context safe for exploring diverse perspectives. The implications of these findings for the science and practice of community psychology are discussed.     

Patterns of neuronal activation in the rat brain and spinal cord in response to increasing durations of restraint stress

By most accounts the psychological stressor restraint produces a distinct pattern of neuronal activation in the brain. However, some evidence is incongruous with this pattern, leading us to propose that the restraint-induced pattern in the central nervous system might depend on the duration of restraint used. We therefore determined the pattern of neuronal activation (as indicated by the presence of Fos protein) seen in the paraventricular nucleus (PVN), bed nucleus of the stria terminalis, amygdala, locus coeruleus, nucleus tractus solitarius (NTS), ventrolateral medulla (VLM) and thoracic spinal cord of the rat in response to 0, 15, 30 or 60 min periods of restraint. We found that although a number of cell groups displayed a linear increase in activity with increasing durations of restraint (e.g. hypothalamic corticotrophin-releasing factor (CRF) cells, medial amygdala neurons and sympathetic preganglionic neurons of the thoracic spinal cord), a number of cell groups did not. For example, in the central amygdala restraint produced both a decrease in CRF cell activity and an increase in non-CRF cell activity. In the locus coeruleus, noradrenergic neurons did not display Fos in response to 15 min of restraint, but were significantly activated by 30 or 60 min restraint. After 30 or 60 min restraint a greater degree of activation of more rostral A1 noradrenergic neurons was observed compared with the pattern of A1 noradrenergic neurons in response to 15 min restraint. The results of this study demonstrate that restraint stress duration determines the amount and the pattern of neuronal activation seen in response to this psychological stressor.     

Quality and Individualization in Wraparound Team Planning

In children’s mental health, collaborative, team-based individualized service planning is most commonly known as wraparound, and has become one of the primary strategies for improving services and outcomes for children with the highest levels of need. We report on analyses of data gathered at 72 wraparound team meetings from communities around the United States. We describe the composition of the teams and the quality of the planning process they engaged in, and explore the extent to which these factors were associated with team member satisfaction and the individualization of plans. Teams in our study were numerically dominated by professionals. Parents attended a large majority of meetings, participation by youth and family advocates was frequent, participation by other family members infrequent, and participation by other members of the family’s informal or natural support networks rare. Observed teams varied considerably in the quality of their planning process and the degree of individualization of plans. Higher-quality planning was significantly associated with increased individualization of plans and with team member satisfaction with meeting productivity.     

Notional number agreement in English

To investigate the contested role of notional number in English subject-verb agreement, we used a sentence completion task to examine agreement with minimally different subject noun-phrases, such as the gang on the motorcycles and the gang near the motorcycles. These contrasting phrases biased different notional construals of collective nouns, such as gang, which are normally ambiguous between plural (distributed) and singular (collected) construals. With subjects biased toward spatial distribution, such as gang on motorcycles, more plural verbs occurred in speakers’ sentence completions than in sentence completions with a bias toward spatial collection such as gang near motorcycles. This offers strong evidence regarding both the existence and the magnitude of notional effects on subject-verb number agreement in English.
