The effect of long-term working memory through personalization applied to free recall: Uncurbing the primacy-effect enthusiasm

In this study, a personalization method (Guida, Tardieu, & Nicolas, European Journal of Cognitive Psychology, 21: 862–896 2009) was applied to a free-recall task. Fifteen pairs of words, composed of an object and a location, were presented to 93 participants, who had to mentally associate each pair and subsequently recall the objects. A 30-s delay was introduced on half of the trials, the presentation rate was manipulated (5 or 10 s per item), and verbal and visuospatial working memory tests were administered to test for their effects on the serial curve. Two groups were constituted: a personalized group, for whom the locations were well-known places on their university campus, and a nonpersonalized group, for whom the locations did not refer to known places. Since personalization putatively operationalizes long-term working memory (Ericsson & Kintsch, Psychological Review, 102: 211–245 1995)—namely, the capacity to store information reliably and rapidly in long-term memory—and if we take a dual-store approach to memory, the personalization advantage would be expected to be greater for pre-recency than for recency items. Overall, the results were compatible with long-term working memory theory. They contribute to validating the personalization method as a methodology to characterize the contribution of long-term memory storage to performance in working memory tasks.     

Catachrestic Plural Forms. Gregory of Nyssa and Theodore Abū Qurrah on Naming and Counting Essences

The fourth-century thinker and theologian Gregory of Nyssa was a convinced realist about universals. According to him, there is just one substance man for all the individuals of the species man and this universal substance is completely instantiated by each individual. In two of his treatises – the Ad Ablabium and the Ad Graecos – he draws linguistic consequences from this realist position. This enquiry results in the thesis according to which it is incorrect to use natural kind terms (such as names of species) in the plural form, because that would involve stating a plurality of substances, when in fact there is just one substance for all the individuals of a given kind. In consequence, since the substance of all individual human beings is the same, the word ‘man’ can only be used adequately in the singular form. In this contribution, Gregory's reasoning is reconstructed. In the second part of the paper, the posterity of his theory and its endorsement by Theodore Abū Qurrah at the turn of the eighth and ninth centuries are examined.     

Scientists’ Argumentative Reasoning

Reasoning, defined as the production and evaluation of reasons, is a central process in science. The dominant view of reasoning, both in the psychology of reasoning and in the psychology of science, is of a mechanism with an asocial function: bettering the beliefs of the lone reasoner. Many observations, however, are difficult to reconcile with this view of reasoning; in particular, reasoning systematically searches for reasons that support the reasoner’s initial beliefs, and it only evaluates these reasons cursorily. By contrast, reasoners are well able to evaluate others’ reasons: accepting strong arguments and rejecting weak ones. The argumentative theory of reasoning accounts for these traits of reasoning by postulating that the evolved function of reasoning is to argue: to find arguments to convince others and to change one’s mind when confronted with good arguments. Scientific reasoning, however, is often described as being at odds with such an argumentative mechanisms: scientists are supposed to reason objectively on their own, and to be pigheaded when their theories are challenged, even by good arguments. In this article, we review evidence showing that scientists, when reasoning, are subject to the same biases as are lay people while being able to change their mind when confronted with good arguments. We conclude that the argumentative theory of reasoning explains well key features of scientists’ reasoning and that differences in the way scientists and laypeople reason result from the institutional framework of science.     

Dyadic Cross-Sectional Associations Between Negative Mood,Marital Idealization,and Relationship Quality

This study aimed to evaluate (a) dyadic associations between relationship quality (RQ) and both depressive and anxious mood (DM and AM), (b) reciprocity hypotheses of negative mood within dyadic interactions, and (c) mediational role of marital idealization between negative mood and relationship quality. Actor-partner interdependence models (APIMs) were performed using data from a sample of 198 dyads. Our results showed that (a) these two facets of negative mood did not have the same weight on RQ and that they had a gender-specific effects pattern, and (b) there was no support for the mood transmission hypothesis. Men's DM displayed direct and indirect (via marital idealization) actor as well as partner effects on RQ, whereas women's DM displayed only a direct actor effect on RQ. There were no significant direct actor effects of AM on RQ, meaning that this link is fully mediated by marital idealization. However, only women's AM showed such indirect effects on RQ.     

Perceptual grouping affects pitch judgments across time and frequency

Pitch, the perceptual correlate of fundamental frequency (F0), plays an important role in speech, music, and animal vocalizations. Changes in F0 over time help define musical melodies and speech prosody, while comparisons of simultaneous F0 are important for musical harmony, and for segregating competing sound sources. This study compared listeners' ability to detect differences in F0 between pairs of sequential or simultaneous tones that were filtered into separate, nonoverlapping spectral regions. The timbre differences induced by filtering led to poor F0 discrimination in the sequential, but not the simultaneous, conditions. Temporal overlap of the two tones was not sufficient to produce good performance; instead performance appeared to depend on the two tones being integrated into the same perceptual object. The results confirm the difficulty of comparing the pitches of sequential sounds with different timbres and suggest that, for simultaneous sounds, pitch differences may be detected through a decrease in perceptual fusion rather than an explicit coding and comparison of the underlying F0s.     

Using trained pouched rats to detect land mines: another victory for operant conditioning

We used giant African pouched rats (Cricetomys gambianus) as land mine-detection animals in Mozambique because they have an excellent sense of smell, weigh too little to activate mines, and are native to sub-Saharan Africa, and therefore are resistant to local parasites and diseases. In 2009 the rats searched 93,400 m(2) of land, finding 41 mines and 54 other explosive devices. Humans with metal detectors found no additional mines. On average, the rats emitted 0.33 false alarm for every 100 m(2) searched, which is below the threshold given by International Mine Action Standards for accrediting mine-detection animals. These findings indicate that Cricetomys are accurate mine-detection animals and merit continued use in this capacity.     

The Affect Misattribution Procedure: hot or not?

The Affect Misattribution Procedure (AMP; Payne, Cheng, Govorun, & Stewart, 2005) is an important tool in implicit social cognition research, but little is known about its underlying mechanisms. This paper investigates whether, as the name implies, affect-based processes really underlie the AMP. We used a modified AMP that enabled us to separate the influence of affective and nonaffective processes. In three studies, evidence for the implication of nonaffective processes was consistently found. In contrast, there was no evidence for affect-based processes. Thus, the AMP rather seems cold than hot. The generalizability of the results obtained with the modified AMP is discussed.     

Physical self-concept and disturbed eating attitudes and behaviors in French athlete and non-athlete adolescent girls: direct and indirect relations

This study aims to investigate the direct and indirect associations between physical self-subdomains, physical self-worth, global self-worth, and disturbed eating attitudes and behaviors among French non-elite athlete and non-athlete adolescent girls. A sample of adolescent girls including 50 ballet dancers, 41 basketball players, and 47 non-athletes was used in this study. Data obtained from the ballet dancer and basketball player subsamples revealed significant, sample-specific as well as common, direct relations between global and physical self-perceptions and disturbed eating attitudes and behaviors, as well as significant indirect relations (via global self-worth and physical self-worth) between specific physical self-perceptions and disturbed eating attitudes and behaviors. In contrast, no association was found between global and physical self-perceptions in the sample of non-athlete adolescent girls.     

Effects of achievement goals on self-regulation of eating attitudes among elite female athletes: An experimental study

Introduction

The influence of achievement goals on eating attitudes has mainly been examined through correlational studies (e.g., [De Bruin et?al., 2009] and [Duda and Kim, 1997]), and none of the studies to date has focused on the self-regulation of eating attitudes in athletes. The present study experimentally tested the effects of achievement goals on both self-reported (Study 1) and behavioral indices (Study 2) of the self-regulation of eating attitudes in female figure skaters.

Method

Elite female figure skaters (Study 1: n = 44; Study 2: n = 54) were randomly assigned to one of four conditions designed to induce specific goal involvement (performance-approach, mastery-approach, performance-avoidance, and mastery-avoidance) or a control condition (no goal induction). The participants in Study 1 completed the Self-Regulation of Eating Attitudes in Sport Scale (SREASS, Scoffier, Corrion, Paquet, & Arripe-Longueville, 2010) and those in Study 2 completed a virtual behavioral measure of self-regulation of eating attitudes (VSSR; Scoffier, 2009).

Results

Variance analyses indicated that induced mastery-approach goals and performance-avoidance goals resulted in higher scores for self-regulation of eating attitudes than induced performance-approach goals and mastery-avoidance goals. The relationships were the same at both self-reported and behavioral levels.

Discussion

This experimental study confirms the findings of previous correlational works and shows that achievement goals contribute to the causal processes of self-regulation of eating attitudes. These findings might help to prevent eating disorders in female athletes by providing guidance for the development of adapted motivational strategies.
