Universal features of personality traits from the observer's perspective: data from 50 cultures

To test hypotheses about the universality of personality traits, college students in 50 cultures identified an adult or college-aged man or woman whom they knew well and rated the 11,985 targets using the 3rd-person version of the Revised NEO Personality Inventory. Factor analyses within cultures showed that the normative American self-report structure was clearly replicated in most cultures and was recognizable in all. Sex differences replicated earlier self-report results, with the most pronounced differences in Western cultures. Cross-sectional age differences for 3 factors followed the pattern identified in self-reports, with moderate rates of change during college age and slower changes after age 40. With a few exceptions, these data support the hypothesis that features of personality traits are common to all human groups.     

High temporal discounters overvalue immediate rewards rather than undervalue future rewards: An event-related brain potential study

Impulsivity is characterized in part by heightened sensitivity to immediate relative to future rewards. Although previous research has suggested that “high discounters” in intertemporal choice tasks tend to prefer immediate over future rewards because they devalue the latter, it remains possible that they instead overvalue immediate rewards. To investigate this question, we recorded the reward positivity, a component of the event-related brain potential (ERP) associated with reward processing, with participants engaged in a task in which they received both immediate and future rewards and nonrewards. The participants also completed a temporal discounting task without ERP recording. We found that immediate but not future rewards elicited the reward positivity. High discounters also produced larger reward positivities to immediate rewards than did low discounters, indicating that high discounters relatively overvalued immediate rewards. These findings suggest that high discounters may be more motivated than low discounters to work for monetary rewards, irrespective of the time of arrival of the incentives.     

Bigger knows better: Young children selectively learn rule games from adults rather than from peers

Preschoolers' selective learning from adult versus peer models was investigated. Extending previous research, children from age 3 were shown to selectively learn simple rule games from adult rather than peer models. Furthermore, this selective learning was not confined to preferentially performing certain acts oneself, but more specifically had a normative dimension to it: children understood the way the adult demonstrated an act not only as the better one, but as the normatively appropriate/correct one. This was indicated in their spontaneous normative interventions (protest, critique, etc.) in response to third party acts deviating from the one demonstrated by the adult model. Various interpretations of these findings are discussed in the broader context of the development of children's social cognition and cultural learning.     

Promoting responsible conduct: Striving for change rather than consensus

I believe that the ASBMB and the SFN, as well as many scientific, engineering, and other professional societies have taken the right first step. They have taken some responsibility for providing guidelines to their members and others working in related areas. This is how it should be. If professional guidelines are to be meaningful, they must be defined in large part by the practitioners. Yet, having agreed that we need professional societies to become involved, we now must determine the nature of that involvement. I hope that a comparison of the ASBMB and SFN documents will serve to illustrate the differences between two approaches. I cannot be sure that one is better than the other. But I do believe that we should not, cannot, avoid the details. I also believe that to affect change one needs to capture the attention of the audience and to promote active thought—discussion if possible, controversy if necessary. And change is what we need.     

Semantic inhibition of return is the exception rather than the rule

Inhibition of return (IOR) has recently been reported for lexical/semantic categories (see, e.g., Fuentes, Vivas, & Humphreys, 1999). The present research examines the impact on semantic IOR of three components: item repetition, item heterogeneity, and spatial variability. Experiments 1 and 2 indicate that lexical/semantic IOR occurs only after extensive repetition. Experiment 2 also shows that semantic IOR is independent of spatial variability. Experiments 3 through 5 show facilitatory rather than inhibitory effects when the item pool is heterogeneous. The results support an episodic account of semantic IOR, according to which inhibitory effects accumulate with massive repetition of homogeneous items.     

Unconsciously induced song recall: The process of unintentional rather than so-called spontaneous evocations of music

Summary and Conclusions This paper has presented the basis for a reformulation of the traditional psychoanalytic usage of the termspontaneous evocations. Illustrated with a supervisory example, I have argued for a return to Freud’s original use of the wordunintentional or to equivalent synonyms. The process whereby such unexpected music evocations appear in consciousness has been termed “unconsciously induced song recall.” The role of serendipity in this theoretical reformulation will be addressed separately (see Díaz de Chumaceiro, 1995; Díaz de Chumaceiro and Yáber, 1994). Like dreams, music evocations can be subjected to analysis and interpretation, if when recalled by indirect or direct induction in treatment they are mentioned to the therapist. This baisc principle of induced recall can be generalized to evocations of the art world at large. Cora L. Díaz de Chumaceiro, Ph.D., is a Clinical Psychologist in private practice in Caracas, Venezuela. She is also Editorial Board Member ofThe Arts in Psychotherapy.     

Better explanations of lexical and semantic cognition using networks derived from continued rather than single-word associations

In this article, we describe the most extensive set of word associations collected to date. The database contains over 12,000 cue words for which more than 70,000 participants generated three responses in a multiple-response free association task. The goal of this study was (1) to create a semantic network that covers a large part of the human lexicon, (2) to investigate the implications of a multiple-response procedure by deriving a weighted directed network, and (3) to show how measures of centrality and relatedness derived from this network predict both lexical access in a lexical decision task and semantic relatedness in similarity judgment tasks. First, our results show that the multiple-response procedure results in a more heterogeneous set of responses, which lead to better predictions of lexical access and semantic relatedness than do single-response procedures. Second, the directed nature of the network leads to a decomposition of centrality that primarily depends on the number of incoming links or in-degree of each node, rather than its set size or number of outgoing links. Both studies indicate that adequate representation formats and sufficiently rich data derived from word associations represent a valuable type of information in both lexical and semantic processing.     

'Nonspecific' rather than 'nonassociative' pathways to phobias: a commentary on Poulton and Menzies

This commentary attempts to clarify the nature of contemporary associative accounts of phobias, and to describe how they might contribute to the explanation of the diversity of phobic aetiologies. It is argued that conditioning-equivalent associations underpin all phobic conditions, and that the role of experimental psychopathology research is to determine how these associations are acquired. The commentary then proceeds to discuss some of the theoretical problems with the nonassociative account of phobias as it is currently described by Poulton and Menzies, and to suggest that some interpretations of their retrospective and prospective data may not be incompatible with contemporary associative accounts. The outcome of this is that it may be more suitable to describe the fourth pathway to phobia acquisition described by Poulton and Menzies as a 'nonspecific' rather than a 'nonassociative' pathway.     

The key to cultural innovation lies in the group dynamic rather than in the individual mind

Vaesen infers unique properties of mind from the appearance of specific cultural innovation--a correlation without causal direction. Shifts in habitat, population density, and group dynamics are the only independently verifiable incentives for changes in cultural practices. The transition from Acheulean to Late Stone Age technologies requires that we consider how population and social dynamics affect cultural innovation and mental function.     

The comprehension of action-related sentences may cause interference rather than facilitation on matching actions

This study used a dual-task paradigm to analyze the time course of motor resonance during the comprehension of action language. In the study, participants read sentences describing a transfer either away from (“I threw the tennis ball to my rival”) or toward themselves (“My rival threw me the tennis ball”). When the transfer verb appeared on the screen, and after a variable stimulus onset asynchrony (SOA), a visual motion cue (Experiment 1) or a static cue (Experiment 2) prompted participants to move their hand either away from or toward themselves to press a button. The results showed meaning–action interference at short SOAs and facilitation at the longest SOA for the matching conditions. These results support the hypothesis that motor processes associated with the comprehension of action-related language interfere with an overlapping motor task, whereas they facilitate a delayed motor task. These effects are discussed in terms of resonance processes in the motor cortex.     

"Be the love of god rather than talk about it": ministers study psychology

After World War II, American ministers successfully drew on training in psychology to nurture their spiritual and vocational development. Contrary to what critics of a therapeutic ethos in American culture have asserted, this social history of ministers shows that their adoption of psychological modes of thinking was neither atomizing nor secularizing. Rather, it helped them become better people and better ministers. It nurtured their faith as well as their social connections. Thus, I argue against critics who have feared the civically enervating effects of psychological outlooks in American society.     

Unprejudiced and self-focused: When intergroup contact is experienced as being about the ingroup rather than the outgroup

Many problematic responses that occur in intergroup interaction, such as inhibited behavior, restricted disclosure of valuable information, and miscommunication, do not arise from negative attitudes and sometimes are more frequently exhibited by lower-prejudice individuals. Thus it is important to consider how lower-prejudice individuals respond to methods for improving intergroup relations that have been investigated with the prejudiced person in mind. Two studies tested the hypothesis that for lower-prejudice individuals intergroup contact is experienced as being about the ingroup rather than the outgroup, and thus fails to exert its usual effect of paving the way for more positive subsequent intergroup exchanges. As predicted, for individuals seeking to be unbiased an initial exchange with one outgroup member affected feelings about ingroup worthiness, but not reactions to a subsequently encountered outgroup member. The opposite pattern was evident for higher-prejudice individuals, who readily generalized from their experience with one outgroup member to the next.

The observer's acquaintance with the model's stimulus in vicarious classical conditioning

To disentangle possibel mediating mechanisms in vicarious learning, the observer's acquaintance with an annoying stimulus was varied before taking part in a classical conditioning procedure where the model ostensible received strong electric shocks. For a total 64 observers of both sexes the pre-conditioning acquaintance was varied in a 2times2 factorial design with Intensity (strong/week) and Modality (shock/tone) as independent variables. In the differential long interstimulus interval conditioning procedure, skin conductance responses (SCRs) were employed as the main dependent measure, and were supplemented by post-experimental questionnaire ratings. Data analyses indicated that the observers with a weak intensity of pre-experimental acquaintance conditioned SCRs better than those with a strong intensity, which was contrary to hypotheses. For the post-experimental ratings no such effect was indicated. The results are discussed in terms of the observer's perceived self-suffering to the model's stimulus and the intensity of the model's emotional state as perceived by the observer. It is argued that the groups with a strong intensity of pre-experimental discomfort preceived the model's emotional state as less intense than the groups who had encountered a weak intensity stimulus.     

Lab support for strong reciprocity is weak: punishing for reputation rather than cooperation

Strong reciprocity is not the only account that can explain costly punishment in the lab; it can also be explained by reputation-based accounts. We discuss these two accounts and suggest what kinds of evidence would support the two different alternatives. We conclude that the current evidence favors a reputation-based account of costly punishment.     

Banking on brains: Insights of brain donor relatives and friends from an experiential perspective

Brain donation is critical to understand the pathological causes of neurodegenerative diseases. Increasing levels of donation requires an understanding of those factors that both encourage and deter donation. At present, there are few studies of how people understand, feel and decide about brain donation for scientific research. This qualitative experiential study contributes to the growing literature on brain donation through its specific focus on how the donation process is experienced from the perspectives of family members and friends. Nineteen semi-structured interviews were analysed using a phenomenologically informed thematic analysis. Four themes were derived from the analysis, three of which are described in detail: Making the decision to donate; a personal perspective on the donation process; the significance of the brain; beliefs about brain donation. In particular, the thematic analysis highlights the variation of individual decision making and the emotions and reasons underpinning such decisions. Key conclusions include the importance of integrated practice amongst relevant healthcare professionals as well as the need for supportive and informed communication. Also, in light of the finding that the brain assumed no special significance for most participants, the value of the distinction between brain donation for research purposes and organ transplantation is questioned.     

Memory systems of the brain: a brief history and current perspective

The idea that memory is composed of distinct systems has a long history but became a topic of experimental inquiry only after the middle of the 20th century. Beginning about 1980, evidence from normal subjects, amnesic patients, and experimental animals converged on the view that a fundamental distinction could be drawn between a kind of memory that is accessible to conscious recollection and another kind that is not. Subsequent work shifted thinking beyond dichotomies to a view, grounded in biology, that memory is composed of multiple separate systems supported, for example, by the hippocampus and related structures, the amygdala, the neostriatum, and the cerebellum. This article traces the development of these ideas and provides a current perspective on how these brain systems operate to support behavior.     

The duality principle: irreducibility of sub-threshold psychophysical computation to neuronal brain activation

A key working hypothesis in neuroscience is ‘materialistic reductionism’, i.e., the assumption whereby all physiological, behavioral or cognitive phenomena is produced by localized neurochemical brain activation (but not vice versa). However, analysis of sub-threshold Weber’s psychophysical stimulation indicates its computational irreducibility to the direct interaction between psychophysical stimulation and any neuron/s. This is because the materialistic-reductionistic working hypothesis assumes that the determination of the existence or non-existence of any psychophysical stimulation [s] may only be determined through its direct interaction [di1] with a given neuron/s [N] that together forms the ‘neural registry’ computational level [NR/di1]. But, this implies that in cases of (initial) sub-threshold (sensory-specific) psychophysical stimulation which is increased above the sensory-specific threshold but below Weber’s psychophysical ‘dv’—the psychophysical computational processing [PCP] produces an apparently ‘computationally indeterminate’ output. This is because materialistic reductionism asserts the contingency of PCP upon the existence of a direct interaction between ‘s’ and ‘N’ within the NR/di1 level, but in the special case of Weber’s sub-threshold psychophysical stimulation the same PCP/di1 also asserts the non-existence of ‘s’ (as demanded by Weber’s psychophysical law). However, given robust empirical evidence indicating the capability of PCP to determine whether (or not) ‘s’ exists, we must conclude that PCP may not be carried out from within NR’s direct interaction between a particular psychophysical stimulation and any set of neuron/s in the brain. Hence, the Duality Principle asserts the conceptual irreducibility of sub-threshold psychophysical stimulation to any direct NR/di1: s-N interaction, thereby challenging the current materialistic-reductionistic assumption.
