The Hebb repetition effect as a laboratory analogue of novel word learning

The present study tests the hypothesis that a common ordering mechanism underlies both short-term serial recall of verbal materials and the acquisition of novel long-term lexical representations, using the Hebb repetition effect. In the first experiment, participants recalled visually presented nonsense syllables following a typical Hebb effect learning protocol. Replicating the Hebb repetition effect, we observed improved recall for repeated sequences of syllables. In the second experiment, the same participants performed an auditory lexical decision task, which included nonwords that were constructed from the syllables used in the first experiment. We observed inhibited rejection of nonwords that were composed of the repeated Hebb sequences, compared to nonwords that were built from nonrepeated filler sequences. This suggests that a long-term phonological lexical representation developed during Hebb learning. Accordingly, the relation between immediate serial recall and word learning is made explicit by arguing that the Hebb repetition effect is a laboratory analogue of naturalistic vocabulary acquisition.     

Gender perspective in the context of Spanish academic psychology

The purpose of this study is to analyse the evolution of gender perspective in the context of the Spanish academic Psychology. The last three decades were analysed. In each decade, the study describes the groups and individuals who have contributed to the analysis of gender perspective in Psychology, the sponsoring institutions, and the most frequently used research strategies. Likewise, the study analyses the development of topics and areas in these three decades. The general trend shows that the interpretation of sex/gender has moved away from being considered an individual and internal factor to a more dynamic approach that analyses sex/gender through behavioural practices.     

Fact learning: how information accuracy, delay, and repeated testing change retention and retrieval experience

Previous classroom studies have shown that the phenomenology of studied facts changes over time. However, pedagogical needs preclude both the study of errors and the separation of the effects that delay and repeated testing have on retention and retrieval experience. We addressed these issues together in an experiment where participants read stories containing correct and misleading information and provided Remember, Just Know, and Familiar judgements on immediate and delayed general knowledge tests. After 2 days, information learned from the stories shifted from Remembered to Just Known, but repeated testing attenuated this shift. Interestingly, similar patterns of retrieval and phenomenology were observed for correct and misleading information with one important difference--the shift over time to Just Knowing was significantly greater for correct than for misleading information. Together, these findings show the roles of information accuracy, delay, and testing in determining both retention and the subjective experience of retrieval.     

Learning and memory deficits in mice lacking protease activated receptor-1

The roles of serine proteases and protease activated receptors have been extensively studied in coagulation, wound healing, inflammation, and neurodegeneration. More recently, serine proteases have been suggested to influence synaptic plasticity. In this context, we examined the role of protease activated receptor 1 (PAR1), which is activated following proteolytic cleavage by thrombin and plasmin, in emotionally motivated learning. We were particularly interested in PAR1 because its activation enhances the function of NMDA receptors, which are required for some forms of synaptic plasticity. We examined several baseline behavioral measures, including locomotor activity, expression of anxiety-like behavior, motor task acquisition, nociceptive responses, and startle responses in C57Bl/6 mice in which the PAR1 receptor has been genetically deleted. In addition, we evaluated learning and memory in these mice using two memory tasks, passive avoidance and cued fear-conditioning. Whereas locomotion, pain response, startle, and measures of baseline anxiety were largely unaffected by PAR1 removal, PAR1-/- animals showed significant deficits in a passive avoidance task and in cued fear conditioning. These data suggest that PAR1 may play an important role in emotionally motivated learning.     

A Moment of Unconditional Validity? Schutz and the Habermas/Rorty Debate

Richard Rorty challenges Jurgen Habermas's belief that validity-claims raised within context-bound discussions contain a moment of universality validity. Rorty argues that immersion within contingent languages prohibits any neutral, context-independent ground, that one cannot predict the defense of one's assertions before any audience, and that philosophy can no more escape its contextual limitations than strategic counterparts. Alfred Schutz's phenomenological account of motivation, the reciprocity of perspectives, and the theoretical province of meaning can articulate Habermas's intuitions.Since any claim can be analyzed from an observer's perspective for its because-motives, it can always be shown to be context-related; but to the participant involved in the in-order-to project of establishing a claim's validity, the claim appears objectively valid until counter-evidence surfaces. Rorty, even when explaining what it is to make a truth claim, resorts to the observer perspective and omits reference to the in-order-to perspective, within which alone unconditional validity becomes visible. Furthermore, the expectation that one's claim is universally valid depends not on an empirical prediction that one's claim can survive hypothesized future possible audiences. Rather, because of the reciprocity of perspectives, making possible communication and a common life, theoreticians assume that others will recognize what they take to be objective or valid, independently of diverse biographical circumstances. Finally, within the theoretical province requiring relevances different from those of everyday life, philosophy articulates claims with a greater potential to arrive at universal validity than projects that aim less universally, in spite of the fact that its theoretical context is always susceptible to because motive analysis.     

Youth suicide: insights from 5 years of Arizona Child Fatality Review Team data

Data on 153 youth suicides in Arizona (1994-1999) were used to explore demographic, behavioral, and experiential factors that distinguish between firearm suicide and suicide by other means. In bivariate analyses, White youths were more likely than non-White youths to use a firearm to commit suicide as were youths who had not experienced a life crisis or expressed suicidal thoughts in the past, relationships that hold in multivariate analyses at the p < 0.2 level. Targeted suicide prevention activities should supplement interventions focused on restricting access to highly lethal means of suicide such as firearms.     

A Developmental Approach to the Supervision of Therapists in Training

Supervision is considered essential to therapeutic effectiveness yet trainees frequently report negative supervisory experiences. Although such experiences may be due to inadequate or poor supervision, more often they result from differing needs or expectations among trainees. Thus, supervisors must struggle to determine how to best conduct supervision. We propose that many negative experiences result from a supervisors inattention to the trainees development as a mature individual. By examining the cognitive and emotional development of trainees supervisors are offered a framework from which to select interventions and strategies that encourage rather than discourage trainees.     

Gender Mainstreaming and Healthcare Policy

This review addresses how The Palgrave Handbook of Gender and Healthcare structures and analyzes the themes that emerge from its own interrogation of the complex concepts of gender, equality, health and policy. Overall the review takes a complimentary tone towards the handbook's arguments and premises and the unique research that sets it apart from other more scientifically or development based gender health texts. It points out, however, that the book maintains its focus on the global north and the efficacy of state policy as the primary tool for gender equality, however defined. The author suggests that in future discussions, the alternative routes and different countries that are only just touched on in the text should be more thoroughly explored.
