Cognitive control in number processing: evidence from the unit-decade compatibility effect

In this study we evaluated whether the reverse compatibility effect observed when participants compare two-digit Spanish number words might be modulated as a function of the percentage of filler trials (within-decade comparisons). The participants performed a comparison task with two-digit Spanish number words while the unit–decade compatibility in between decade comparison trials was manipulated. We biased the relevance of units by increasing the intra/inter decade comparison ratio (20%, 50%, and 70%). The compatibility effect shifted from reverse to regular depending on the unit relevance which indicates that the relative emphasis on the unit processing in two-digit number word can be modulated by the stimulus list. These results are discussed in terms of cognitive control in number processing.     

The impact of school-based mentoring on youths with different relational profiles

Associations between youths' relationship profiles and mentoring outcomes were explored in the context of a national, randomized study of 1,139 youths (54% female) in geographically diverse Big Brothers Big Sisters school-based mentoring programs. The sample included youths in Grades 4-9 from diverse racial and ethnic backgrounds, the majority of whom were receiving free or reduced-price lunch. Latent profile analysis, a person-oriented approach, was used to identify 3 distinct relational profiles. Mentoring was found to have differential effects depending on youths' preintervention approach to relationships. In particular, youths who, at baseline, had satisfactory, but not particularly strong, relationships benefited more from mentoring than did youths with profiles characterized by either strongly positive or negative relationships. Implications for research and practice are discussed.     

Situational affect and temperament: Implications for sibling caregiving

The caregiving behaviour of 60 preschool‐age children (M=50 months) toward their 16‐month‐old younger siblings was observed during a brief separation from their parents. Sibling caregiving was more strongly associated with parent ratings of both the older siblings' and toddlers' temperament than with the younger siblings' distress exhibited during the separation. The older siblings' social fear was positively related to providing care, whereas their temperamental activity level was negatively related to caregiving. Younger siblings' temperamental anger and soothability were positively associated with receiving care from an older sibling. Relations with temperament were independent of both children's distress levels during the separation, and in several instances, dispositional affective measures (i.e. temperament) made stronger contributions to the prediction of sibling caregiving than did situational distress.

Perceived collective continuity and social well‐being: exploring the connections

Research has shown that people tend to perceive the groups to which they belong (e.g., national groups) as temporally persistent. In this paper we argue that enhanced perceptions of collective continuity lead to lower levels of anomy and misfit, and to higher levels of social well‐being (SWB). Furthermore, we argue that the effects of perceived collective continuity (PCC) on SWB are mediated by collective self‐esteem (CSE). Finally, we contend that PCC has positive effects on perceived group entitativity (PGE), which in turn has a positive influence on CSE. This model is tested by means of a cross‐sectional study using a sample of Spanish nationals (N = 145) drawn from the general public. Results confirm that the data fit the model well. These findings are in line with research demonstrating that a sense of personal continuity through time is related with better mental health and personal well‐being.

Ethics, deception, and 'Those Milgram experiments'

Critics who allege that deception in psychology experiments is unjustified frequently cite Stanley Milgram's 'obedience experiments' as evidence. These critics say that arguments for justification tend to downplay the risks involved and overstate the benefits from such research. Milgram, they add, committed both sins. Critics are right to point out that research oversight is often susceptible to self-serving abuse. But stating a priori how beneficial a given experiment will be is a tall order for psychologists, or anyone else. At the same time, critics themselves have difficulty in showing what is wrong with deception, and how subjects in these experiments suffer. Hence, it becomes unclear what the psychologists, including Milgram, are prone to downplay. There is also room to wonder how the Milgram studies can illuminate the debate over deception. Although Milgram probably exaggerated the scientific significance of his own work, critics who exaggerate its moral and historical significance do little to clarify the status of deception.     

Naming digits in a semantic blocking paradigm

It is widely agreed that word numerals are processed similar to other words, and, thus, they can be named without semantic mediation. However, there is no consensus about Arabic digits. Although digits seem to have a preferential link to magnitude representation, there is some evidence indicating a possible asemantic route to access phonological information. In the present study, we used a semantic blocking paradigm to explore this question. In Experiment 1, participants were asked to name digits and pictures or numeral words and name of objects in a semantic blocked context and in a mixed context. For both types of numerical notation we found facilitation in the blocked condition relative to the mixed condition. In Experiment 2, participants named two-digit numbers in a blocked condition (short numerical distance) or in a mixed condition (large numerical distance). Again, facilitation was found for the blocked condition relative to the mixed condition. This pattern of results seems to indicate that Arabic digits, like number words, might be named through an asemantic route.     

Greater family identification—but not greater contact with family members—leads to better health: Evidence from a Spanish longitudinal study

We investigated the effect of family identification (one's subjective sense of belonging to and commonality with the family) on self‐reported ill‐health in 206 Valencian undergraduates, with eight months between Time 1 (T1) and Time 2 (T2). While greater family identification T1 predicted lower ill‐health T2, ill‐health T1 did not predict family identification T2. Family contact T1 (one's intensity of interaction with family) was unrelated to ill‐health T2. This shows that family identification impacts positively on health over time (rather than health impacting positively on family identification over time), and this is not reducible to effects exerted by family contact. These findings indicate that encouraging patients to engage in group activities might produce negligible health gains unless the patient identifies with the group in question.     

Some ways that technology and terminology distort the euthanasia issue

Technology and terminology often detract from a reasoned appraisal of the euthanasia option, especially in those discussions that argue for euthanasia's incorporation into a beneficence-based medical model. “Beneficent euthanasia,” assuming there is such a thing, poses special challenges to the traditional provider-patient relationship. These challenges argue for well-defined limits of beneficence and a more equitable distribution of responsibility between participants. We should not allow technology and terminology to generate an unrealistic portrayal of patient death and its ramifications. Participants need to acknowledge their roles in the decision to kill and the obligations that those roles entail. Perhaps we can reach ethical consensus concerning euthanasia by first reasserting our span of control over the technology that can extend the near-death period and by openly discussing euthanasia's implications.     

Perceived collective continuity and ingroup identification as defence against death awareness

Perhaps unique among the animal species, humans are aware that they will ultimately die. Terror management theory (TMT) posits that investing in a social group helps people to manage paralysing anxiety stemming from death awareness. In line with this proposition, research to date has shown that when reminded of their own mortality, people increase their identification with a relevant group and defend its beliefs, values, and practices. In the reported study, we demonstrate that a mortality salience induction enhances people’s perceptions of group temporal endurance—or perceived collective continuity (PCC), as we define it. Enhanced PCC leads, in turn, to enhanced group identification. This is in line with the TMT assumption that death awareness leads people to invest in a social group because this constitutes a temporally enduring meaning-system that imbues life with meaning, order, and permanence, and promises death transcendence to those who meet the prescribed standards of value.
