Soliciting Charity Contributions: The Parlance of Asking for Money1

The major purpose of this study was to investigate the effects of three verbally-mediated variables on financial contributions in a door-todoor charity campaign. The relationship of race to contributions was also observed by using both black and white subjects. One hundred and twenty black and 120 white subjects were randomly assigned to one of 8 verbal appeals in a 2 (High vs. Low Dependency) × 2 (Internal vs. External Causal Locus of Need) × 2 (“it is your social responsibility” vs. “it will make you feel good” Expressed Reason for Giving) factorial design. The solicitor controlled for order effects by varying the sequence of these three variables within each experimental group. Main effects were found for Rae, Causal Locus of Need, and Expressed Reason for Giving: Whites contributed more than blacks, the external locus of need condition produced more giving than the internal condition, and persons who heard the “feel good” reason donated more than those in the “social responsibility” condition. Additionally, a significant Causal Locus of Need × Expressed Reason for Giving interaction was found. The combination of external locus of need and “feel good” was considerably more productive of contributions than the other three combinations. Implications of these results for the helping behavior literature are discussed.     

Increasing magnitude counts more: asymmetrical processing of ordinality in 4-month-old infants

While infants' ability to discriminate quantities has been extensively studied, showing that this competence is present even in neonates, the ability to compute ordinal relations between magnitudes has received much less attention. Here we show that the ability to represent ordinal information embedded in size-based sequences is apparent at 4months of age, provided that magnitude changes involve increasing relations. Infants in Experiments 1A and 1B discriminated changes in ordinal relations after habituation to ascending sequences, but did not show evidence of discrimination after habituation to descending sequences. In Experiment 2 we replicated this asymmetry in magnitude discrimination even when additional cues known to boost ordinal competence were provided. The presence of an asymmetry between ascending vs. descending order during infancy suggests a developmental continuity in the underlying code used to represent magnitude, whereby the reported addition advantage in children and adults' arithmetic performance emerges.     

Social Capital and Individual Happiness in Europe

This paper explores the relationship between social capital and happiness both in Europe as a whole, as well as in its four main geographical macro-regions—North, South, East and West—separately. We test the hypothesis of whether social capital, in its three-fold definition established by Coleman (Am J Sociol 94:S95–S120 1988)—trust, social interaction, and norms and sanctions—influences individual happiness across European countries and regions. The concept of social capital is further enriched by incorporating Putnam (Making democracy work—civic traditions in modern Italy. Princeton University Press, Princeton, 1993) and Olson (The rise and decline of nations—economic growth, stagflation, and social rigidities. Yale University Press, New Haven and London, 1982) type variables on associational activity. Using ordinal logistic regression analysis on data for 48,583 individuals from 25 European countries, we reach three main findings. First, social capital matters for happiness across the three dimensions considered. Second, the main drivers of the effects of social capital on happiness appear to be informal social interaction and general social, as well as institutional trust. And third, there are significant differences in how social capital interacts with happiness across different areas of Europe, with the connection being at is weakest in the Nordic countries.     

The own‐age face recognition bias is task dependent

The own‐age bias (OAB) in face recognition (more accurate recognition of own‐age than other‐age faces) is robust among young adults but not older adults. We investigated the OAB under two different task conditions. In Experiment 1 young and older adults (who reported more recent experience with own than other‐age faces) completed a match‐to‐sample task with young and older adult faces; only young adults showed an OAB. In Experiment 2 young and older adults completed an identity detection task in which we manipulated the identity strength of target and distracter identities by morphing each face with an average face in 20% steps. Accuracy increased with identity strength and facial age influenced older adults' (but not younger adults') strategy, but there was no evidence of an OAB. Collectively, these results suggest that the OAB depends on task demands and may be absent when searching for one identity.     

Transforming roles to support student development of academic literacies: a reflection on one team’s experience

Social work is a discipline that attracts students from diverse academic backgrounds. Many are first in family to attend university, and come to university through alternative pathways such as vocational education. As a result, there are higher levels of attrition compared to other disciplines, especially in the first year. To address this, and in keeping with a commitment to provide accessible education, one school of social work undertook a project to embed academic literacies into the curriculum. This paper used Gibb’s reflective process to explore how this was experienced by team members. Data were collected via staff focus groups at two different points in time across the project and compared. The reflection unpacked a number of tensions experienced by team members, including concerns about potential loss of resources as a result of academics adopting new roles, and concerns about implementing what was seen as Westernised academic skills which may not fit with students’ ways of thinking and creating knowledge. Overfull curricula and constant change also appeared to be of concern. The reflection highlighted that to achieve effective and sustainable change, action was required at multiple levels.     

Fitts' Law is Applicable to Trunk Coordination Measurements in a Sitting Position

Trunk coordination is essential for many activities of daily living in wheelchair users. This study investigated whether Fitts' law is applicable to trunk movements in a sitting position. Fourteen healthy adults performed two series of 24 tasks of trunk flexion–extension movements in a sitting position. The results showed significant linear relationships between average group movement time (MT) and index of difficulty (ID) over all tasks (r² = 0.92) and within target distances (0.94 < r² < 1.00). Target distance affected intercept and slope (P < 0.001). Hence, Fitts' law is applicable to the studied trunk movements in a sitting position, indicating these trunk movements tasks could serve as a basis for qualitative trunk coordination tests. Transferability of these conclusions to wheelchair users, and optimal test design should be further investigated.     

PKMzeta inactivation induces spatial familiarity

Spatial familiarization consists of a decrease in the exploratory activity over time after exposure to a place. Here, we show that a 30-min exposure to an open field led to a pronounced decrease in the exploratory behavior of rats, generating context familiarity. This behavioral output is associated with a selective decrease in hippocampal PKMzeta levels. A short 5-min exposure did not induce spatial familiarity or a decrease in PKMzeta, while inactivation of hippocampal PKMzeta by the specific inhibitor ZIP was sufficient to induce spatial familiarity, suggesting that the decrease in PKMzeta is involved in setting a given context as a familiar place.     

Attentional requirements for object-location priming

The purpose of the present experiments was to investigate whether a verbal and a spatial secondary task would disrupt priming for object-location associations. Symbols were placed one at a time in one of nine locations in a rectangle. Implicit memory was tested with a reaction time (RT) task. All symbols were placed in the same location of the rectangle across 10 trial blocks; then, all their locations were changed. Responses were made on the numeric keypad, which corresponded to the spatial locations used in the rectangle. A decrease in RTs across the first 10 trial blocks followed by an increase in RTs when the symbols changed locations would indicate priming for the associations. The results were that implicit memory for object-location associations was obtained under single-, but not under dual-task conditions. We have interpreted the results in terms of a working memory model that posits that implicit memory will suffer when cognitive resources are limited.
