A challenging dissociation in masked identity priming with the lexical decision task

The masked priming technique has been used extensively to explore the early stages of visual-word recognition. One key phenomenon in masked priming lexical decision is that identity priming is robust for words, whereas it is small/unreliable for nonwords. This dissociation has usually been explained on the basis that masked priming effects are lexical in nature, and hence there should not be an identity prime facilitation for nonwords. We present two experiments whose results are at odds with the assumption made by models that postulate that identity priming is purely lexical, and also challenge the assumption that word and nonword responses are based on the same information. Our experiments revealed that for nonwords, but not for words, matched-case identity PRIME–TARGET pairs were responded to faster than mismatched-case identity prime–TARGET pairs, and this phenomenon was not modulated by the lowercase/uppercase feature similarity of the stimuli.     

Reconsolidation of declarative memory in humans

The reconsolidation hypothesis states that a consolidated memory could again become unstable and susceptible to facilitation or impairment for a discrete period of time after a reminder presentation. The phenomenon has been demonstrated in very diverse species and types of memory, including the human procedural memory of a motor skill task but not the human declarative one. Here we provide evidence for both consolidation and reconsolidation in a paired-associate learning (i.e., learning an association between a cue syllable and the respective response syllable). Subjects were given two training sessions with a 24-h interval on distinct verbal material, and afterward, they received at testing two successive retrievals corresponding to the first and second learning, respectively. Two main results are noted. First, the first acquired memory was impaired when a reminder was presented 5 min before the second training (reconsolidation), and also when the second training was given 5 min instead of 24 h after the first one (consolidation). Second, the first retrieval proved to influence negatively on the later one (the retrieval-induced forgetting [RIF] effect), and we used the absence of this RIF effect as a very indicator of the target memory impairment. We consider the demonstration of reconsolidation in human declarative memory as backing the universality of this phenomenon and having potential clinical relevance. On the other hand, we discuss the possibility of using the human declarative memory as a model to address several key topics of the reconsolidation hypothesis.     

Distress in response to emotional and sexual infidelity: evidence of evolved gender differences in Spanish students

The authors studied gender differences in response to hypothetical infidelity in Spanish students. Using a forced-choice methodology, the authors asked a sample of 266 participants to indicate which kind of infidelity would be more distressing: emotional or sexual. Men were significantly more distressed by sexual infidelity than were women, and women were significantly more distressed by emotional infidelity than were men. Results supported the hypothesis that particular infidelity types, which resemble adaptive problems that human beings faced in the past, contribute to the psychology of jealousy. The results are consistent with previous cross-cultural research.     

Bobwhite quail (Colinus virginianus) hatchlings track the direction of human gaze

Gaze following allows individuals to detect the locus of attention of both conspecifics and other species. However, little is known about how this ability develops. We explored the emergence of bobwhite quail hatchlings’ ability to track human gaze by assessing their avoidance behavior in an open arena under five testing conditions: (1) a Direct Gaze condition, in which an experimenter looking down was positioned above one of two approach areas; (2) a Gaze Follow condition in which an experimenter, positioned equidistant between two approach areas, directed his/her gaze towards one of the areas; (3) a Masked Gaze Follow condition, in which the experimenter wore a mask during the Gaze Follow test; (4) a Deprived Face Experience condition, in which hatchlings were deprived of experience with human faces prior to the Gaze Follow test; and (5) a Control condition in which no experimenter was present during testing. Results revealed that hatchlings from the Direct Gaze condition preferred the non-gazed approach area at all ages tested. Hatchlings from the Gaze Follow condition preferred the non-gazed approach area at 48 and 72 h, but not at 24 h of age. In contrast, hatchlings from the Masked Gaze Follow, Deprived Face and Control conditions did not prefer either approach area at any age tested. These results indicate that experience with human faces plays a key role in the rapid emergence of gaze following behavior in bobwhite quail hatchlings.     

A model of the go/no-go task

In this article, the first explicit, theory-based comparison of 2-choice and go/no-go variants of 3 experimental tasks is presented. Prior research has questioned whether the underlying core-information processing is different for the 2 variants of a task or whether they differ mostly in response demands. The authors examined 4 different diffusion models for the go/no-go variant of each task along with a standard diffusion model for the 2-choice variant (R. Ratcliff, 1978). The 2-choice and the go/no-go models were fit to data from 4 lexical decision experiments, 1 numerosity discrimination experiment, and 1 recognition memory experiment, each with 2-choice and go/no-go variants. The models that assumed an implicit decision criterion for no-go responses produced better fits than models that did not. The best model was one in which only response criteria and the nondecisional components of processing changed between the 2 variants, supporting the view that the core information on which decisions are based is not different between them.     

Political Psychology as Social Aesthetics

Political psychology may be legitimately developed as a "social aesthetic.&;rdquo; Its activities generate social forms, much as in the arts. While logic works within the confines of society's language, aesthetic forms work with its sensibility, in the understanding that significance lies within the unitary wholes. In this sense, political psychology cannot be separated from psychology in general. In both cases we participate in the generation of form. However, because these forms enter society in significant ways, reflexive attention must be given to what it is we create. Mechanical forms, which are common to the field and to society generally, contribute to a condition of social alienation; in contrast, the form of a game is more closely related to the spontaneous creation of community.     

The taken-for-granted world: A study of the relationship between A. Schutz and J. Ortega y Gassed

This paper is a comparative study of Alfred Schutz and Jose Ortega y Gasset, with special attention to their respective characterization of social reality. For this purpose, the author draws on the explicit references Schutz and Ortega directed towards one another and develops a critical comparison of their theoretical systems. In addition to the reciprocal references which appear in their published works, valuable documentary evidence is provided by Schutz's letters and, first and foremost, by his marginal notes preserved in his own copy of Ortega y Gasset's Man and People. As far as the critical comparison of Schutz's and Ortega's theories is concerned, the weight of the discussion falls on Ortega's Man and People. A careful reading of this essay allows us to successively invoke the key components of Schutz's phenomenological characterization of the structures of the life-world. According to this strategy, and after some preliminary sections devoted to contextual, biographical, and sociocultural matters, the following topics are comparatively discussed: (1) the philosophical foundations of sociology, with particular attention to Ortega's doctrine of the Other as potential danger; (2) the taken-for-granted dimensions of the social world; (3) the multiple spheres of reality, and their structuration around the fundamental core of the radical reality of the I (for Ortega) or the paramount reality of everyday life, as the intersubjective world of culture (for Schutz); (4) the influence of pragmatism on their theoretical systems; (5) their strikingly similar characterization of the perspectivist stratification of the social world; (6) the inexhaustible complexity of the problem of intersubjectivity. Obviously, the common influence of Husserl, Weber, Scheler, and Bergson casts light upon the comparative consideration of any of these issues.
