Heidegger on desire

In this article is presented a reading of Heidegger in relation to the conception of desire, and its relation to various terms he uses frequently. I argue that the genesis of desire lies in the gap between the fullness of possibility and the poverty of actualization; that inauthentic desire aims at presence, possession, actualization (always insufficient); and that authentic desire aims at the conservation of the possibility-character of being. I also pay attention to the temporality of desire; to the analogy between Kant's emphasis on respect for the law one has freely postulated and Heidegger's emphasis on Dasein's subjection to the possibilities it projects; to possibility as original abundance; and, in principle, to the turning in which desire is evoked in the event of granting, rather than simply produced in the act of projection. Special attention is paid on the German word 'Verlangen', which is related etymologically to the English 'long for', which stands for wanting something very much. But the word is also connected to the word 'long' which is important to get a grip on the notion of desire in Heidegger.     

Conditioned reinforcement: Neglected or outmoded explanatory construct?

The construct of conditioned reinforcement has been challenged over the past two decades, both as an adequate explanation of behavior in various situations (e.g., behavioral chains) in which it was previously regarded as crucial and in terms of the validity of the concept of conditioned value on which it is based. Recent research is reviewed that answers these criticisms and vindicates the importance of the construct. Also discussed are unanswered empirical issues regarding the concept and its implications for behavioral phenomena of major importance for general-process learning theory, such as autoshaping and imprinting.     

Contingency theory and the effect of the duration of signals for noncontingent reinforcement

Rats learned to approach a light that signaled food when food occurred only after the signal, but did not approach the light when food was equally probable regardless of the signal. When food unpaired with the light was preceded by a 5-sec noise, little learning was evident as well, but when the unpaired food was preceded by a 15-sec noise, approach to the light conditioned stimulus readily occurred. These effects of signal duration are similar to those previously obtained with the effect of free food on free-operant behavior and challenge existing theories of contingency effects in Pavlovian conditioning.     

The hippocampus and stress induced 17-OHCS elevations

The physiologic contribution of the limbic brain to emotionally induced stress is still poorly understood. The present study is designed to more specifically evaluate the role of the hippocampus in stress induced plasma 17-OHCS elevations. The conditional reflex to a sequential presentation of tone and shock was used as the stress agent in adult mongrel dogs. Plasma 17-OHCS levels were determined by the Porter-Silber method. Control and stress levels of 17-OHCS were determined before and after unilateral (left) hippocampectomy, and subsequent contralateral (right) hippocampectomy. A unilateral posterior hippocampal lesion partially attenuated (20%) the normal 17-OHCS stress response. In contrast to unilateral lesions, equivalent bilateral posterior hippocampal lesions abolished the normal 17-OHCS stress response. These observations support the thesis that the elevated 17-OHCS levels in response to the conditioning paradigm is dependent on the hippocampus. Furthermore, it is dependent upon the continuity of the hippocampal circuit and not upon the volumetric steroid binding capacity of the hippocampus. These studies also suggest that a unilaterally functioning hippocampus may be adequate to meet the physiologic needs of stress, as reflected by the 17-OHCS response.

The Assessment of Marital Adjustment with Chinese Populations: A Study of the Psychometric Properties of the Dyadic Adjustment Scale

This article presents findings from a study of the psychometric properties of the Dyadic Adjustment Scale (DAS) with 63 Chinese-Americans. The analysis revealed high internal consistency for DAS scores. Coefficient alpha for the total DAS score was r = .93. Convergent validity was established with the Locke-Wallis Marital Adjustment Scale (LWMAT) (r = .87) and divergent validity by evidence of an inverse relationship with the Marital Disaffection Scale (MDS) (r = –.79). Correlations with each measure were found to be (p = 0.01). The result of factor analysis fail to support the presence of four separate subscales. Results show that the global DAS score is of potential utility with Asian samples.     

Effects of intergroup contact and relative gratification vs. deprivation on prejudice on both sides of the U.S./Mexico status divide

A study in the U.S.–Mexican intergroup context examined how collective relative gratification (RG) versus deprivation affects the relationship between intergroup contact and interpersonal closeness and subtle prejudice towards an out-group. Participants were Mexican university students in Mexico (N = 239) and non-Mexican students in California (N = 90). As predicted, Mexicans experienced less gratification/higher relative deprivation (RD), and low quality intergroup contact and expressed lower interpersonal closeness and higher subtle prejudice than U.S. Americans. Differences between countries were larger amongst participants reporting higher RD. Second-stage moderated mediation analysis showed that the mediating effects of contact between country and interpersonal closeness and subtle prejudice, respectively, were larger amongst participants who felt relatively gratified than those who felt relatively deprived. These findings underline the importance of recognizing the moderating effect of differences in the RG versus RD levels of minority and majority groups when anticipating the potential benefits of intergroup contact for prejudice reduction.

The social foundation of executive function

In this study, we propose that infant social cognition may ‘bootstrap' the successive development of domain‐general cognition in line with the cultural intelligence hypothesis. Using a longitudinal design, 6‐month‐old infants (N = 118) were assessed on two basic social cognitive tasks targeting the abilities to share attention with others and understanding other peoples' actions. At 10 months, we measured the quality of the child's social learning environment, indexed by parent's abilities to provide scaffolding behaviors during a problem‐solving task. Eight months later, the children were followed up with a cognitive test‐battery, including tasks of inhibitory control and working memory. Our results showed that better infant social action understanding interacted with better parental scaffolding skills in predicting simple inhibitory control in toddlerhood. This suggests that infants' who are better at understanding other's actions are also better equipped to make the most of existing social learning opportunities, which in turn may benefit future non‐social cognitive outcomes.
