Information-Seeking Practices during the Sexual Development of Lesbian, Gay, and Bisexual Individuals: The Influence and Effects of Coming Out in a Mediated Environment

Constructing a sexual identity is one of the major developmental tasks of adolescence. Applying the Media Practice Model, this study retrospectively examines how self-identifying lesbian, gay, and bisexual (LGB) individuals used media during the commencement of the coming-out process and the effects of media use during this pivotal time of development. Results indicate that the Internet plays a critical role in the development of LGB sexual identities. Heavy users of media during the coming-out process are significantly less likely to communicate openly with their families later in life. However, individuals’ reports of loneliness and self-esteem are not affected. Conclusions suggest that mediated forms of communication can be beneficial for sexual exploration among LGB individuals.     

Life Satisfaction is not a Balanced Estimator of the Good Life: Evidence from Reaction Time Measures and Self-Reported Emotions

A widespread belief in happiness research is that measures of life satisfaction capture the variety of an individual’s experiences along a single favorable—unfavorable dimension. The current article points to a possible violation of this assumption. With a combination of data and theory it argues that life satisfaction is not a balanced reflection of subjective experiences because the evaluation that drives judgments of life satisfaction is tilted towards pleasure and away from engagement. We postulate that feelings of pleasure are overrated in statements of life satisfaction, whereas feelings of engagement are underrepresented. Feelings of engagement and interest are further supposed to be indicators of personal growth. Measures of personal growth and life satisfaction should thus be unrelated. Empirical evidence for our model is provided by self-report and reaction time data from a Norwegian convenience sample (N = 30). Detection latencies for pleasant stimuli correlated significantly with life satisfaction but not with measures of personal growth. Life satisfaction correlated significantly with pleasant experiences, but not with engagement. Personal growth correlated significantly with feelings of engagement. Life satisfaction and personal growth were uncorrelated.     

Functional role theories of representation and content explanation: with a case study from spatial cognition

The aim of this paper is to show that the widespread opinion, according to which functional role theories of representation fail to account for content explanations of human and animal behaviour, cannot be confirmed with respect to each type of functional role theory. Functional resemblance theories (as referred to by O’Brien and Opie in Representation in mind, Elsevier, 2004) allow for content explanations of successfully performed cognitive abilities as much as for explanations of systematic errors resulting from misrepresentation. How functional roles do their explanatory work in actual scientific research examples is shown by a detailed exploration of model assumptions about homing performances based on path integration mechanisms in humans and animals.

同性恋认同发展的理论模型述评

本质论取向的阶段模型和社会建构论取向的影响因素模型是早期的同性恋认同发展理论,两者对性倾向是否为人类的本质属性产生了激烈的争论。当代发展心理学从生态化理论、毕生发展观、生命历程观出发试图对这两种研究取向进行整合,并提出了相应的模型。未来的研究应该注意同性恋认同发展多样性的特点,正确理解对外暴露在认同发展中的作用,并把纵向研究作为以后的研究方向。最后,提出了中国同性恋认同的特点和本土化研究的假设     

儿童心理时间之旅的发展

人类在心理上把自我投射到过去以重新经历过去事件以及把自我投射到未来以预先经历未来事件的能力被称为心理时间之旅。心理时间之旅是认知心理学、认知神经科学、进化心理学、比较心理学、发展心理学等多个学科共同关注的研究领域。目前有关个体心理时间之旅的发展研究表明,心理时间之旅大约出现在儿童3~5岁时。未来有关个体心理时间之旅的发展性研究应从研究范式、研究技术、认知机制、文化差异等方面加以改进。     

FUNCTIONAL ANALYSIS AND TREATMENT OF RUMINATION USING FIXED‐TIME DELIVERY OF A FLAVOR SPRAY

A functional analysis suggested that rumination exhibited by an adult with autism was maintained by automatic reinforcement. Next, a preference assessment with three flavor sprays (i.e., flavored sprays used by dieters) showed that apple pie spray was most preferred. Finally, the effects of fixed‐time delivery of the apple pie spray on levels of rumination were evaluated. The spray reduced rumination, and the participant was taught to self‐administer the spray.     

Fast and accurate calculations for first-passage times in Wiener diffusion models

We propose a new method for quickly calculating the probability density function for first-passage times in simple Wiener diffusion models, extending an earlier method used by [Van Zandt, T., Colonius, H., & Proctor, R. W. (2000). A comparison of two response-time models applied to perceptual matching. Psychonomic Bulletin & Review, 7, 208-256]. The method relies on the observation that there are two distinct infinite series expansions of this probability density, one of which converges quickly for small time values, while the other converges quickly at large time values. By deriving error bounds associated with finite truncation of either expansion, we are able to determine analytically which of the two versions should be applied in any particular context. The bounds indicate that, even for extremely stringent error tolerances, no more than 8 terms are required to calculate the probability density. By making the calculation of this distribution tractable, the goal is to allow more complex extensions of Wiener diffusion models to be developed.     

The mechanism underlying inhibition of saccadic return

Human observers take longer to re-direct gaze to a previously fixated location. Although there has been some exploration of the characteristics of inhibition of saccadic return (ISR), the exact mechanisms by which ISR operates are currently unknown. In the framework of accumulation models of response times, in which evidence is integrated over time to a response threshold, ISR could reflect a reduction in the rate of accumulation for saccades to return locations or an increase in the effective criterion for response. In two experiments, participants generated sequences of three saccades, in response to a peripheral or a central cue. ISR occurred across these manipulations: saccade latency was consistently increased for movements to the immediately previously fixated location. Latency distributions from individual observers were fit with a Linear Ballistic Accumulator model. ISR was best accounted for as a change in the accumulation rate. We suggest this parameter represents the overall desirability of a particular course of action, the evidence for which may be derived from a variety of sensory and non-sensory sources.     

'Reverberation time', dreaming and the capacity to dream

In this paper the author suggests that understanding the roots of the subjective sense of time can throw light on the disturbances in psychic time which are found in particular in the more severe pathologies. She introduces the argument that the roots of the development of the sense of time rest on a primitive sense of time she calls 'reverberation time'. By this notion she refers to the particular quality of the earliest 'back and forth' internalized exchange with the mother in which the auditory dimension plays a significant part. Referring to a wide range of literature and clinical examples, the author thus suggests that the subjective sense of time is created by the reverberation between mother and infant. Disturbances in this area will be reflected in the pathological 'arresting' of time which is observed in the different pathologies and, in particular, around the negotiation of the depressive position and the oedipal situation. Extending this argument, the author goes on to suggest that it is the internalization of this experience of 'reverberation' which lies at the heart of the experience of dreaming; she considers that dreaming understood as an internal dialogue points both to its roots in the relationship to the maternal object and to its fundamental role in psychic life. The author concludes that 'reverberation time' is also the building block of a psychoanalysis, leading to 'unfreezing' psychic time and enabling the reconnection of 'here and now' with 'there and then' in a flexible way which promotes open possibilities, and that this takes place via the analyst's reverie, or time of reverberation.     

Threat causes liberals to think like conservatives

In Study 1, politically liberal college students’ in-group favoritism increased after a system-injustice threat, becoming as pronounced as that of conservatives. Studies 2 and 3 conceptually replicated these results with low preference for consistency [Cialdini, R. B., Trost, M. R., & Newsom, J. T. (1995). Preference for consistency: The development of a valid measure and the discovery of surprising behavioral implications. Journal of Personality and Social Psychology, 69, 318-328.] as a dispositional measure of liberalism. In Study 2, following a mortality salience threat, dispositionally liberal students showed as much conviction in their attitudes toward capital punishment and abortion as dispositional conservatives did. In Study 3, after a mortality salience threat, liberal students became as staunchly unsupportive of homosexuals as conservatives were. The findings that political and dispositional liberals become more politically and psychologically conservative after threats provide convergent experimental support for the [Jost, J. T., Glaser, J., Kruglanski, A. W., & Sulloway, F. J. (2003). Political conservatism as motivated social cognition. Psychological Bulletin, 129 339-375.] contention that conservatism is a basic form of motivated social cognition.
