Weighing Outcomes by Time or Against Time? Evaluation Rules in Intertemporal Choice

Models of intertemporal choice draw on three evaluation rules, which we compare in the restricted domain of choices between smaller sooner and larger later monetary outcomes. The hyperbolic discounting model proposes an alternative‐based rule, in which options are evaluated separately. The interval discounting model proposes a hybrid rule, in which the outcomes are evaluated separately, but the delays to those outcomes are evaluated in comparison with one another. The tradeoff model proposes an attribute‐based rule, in which both outcomes and delays are evaluated in comparison with one another: People consider both the intervals between the outcomes and the compensations received or paid over those intervals. We compare highly general parametric functional forms of these models by means of a Bayesian analysis, a method of analysis not previously used in intertemporal choice. We find that the hyperbolic discounting model is outperformed by the interval discounting model, which, in turn, is outperformed by the tradeoff model. Our cognitive modeling is among the first to offer quantitative evidence against the conventional view that people make intertemporal choices by discounting the value of future outcomes, and in favor of the view that they directly compare options along the time and outcome attributes.     

High Level of Construal and Psychological Distance Reduce Melioration

We examined how level of construal and psychological distance affected performance in a task in which value of alternatives depended on frequency of choice. Melioration, a sub‐optimal choice strategy that fails to take into account such value changes, has been found to be prevalent and difficult to change. Participants repeatedly chose between two buttons to earn as many coins as possible. Button A earned N coins, button B earned N + 3 coins, and N was the number of A presses in the last five trials. In this situation, B has a higher immediate payoff, but because choosing A increases the return from both buttons for the next five trials, maximizing A choices is the optimal strategy. We predicted that because a global perspective is needed to appreciate the dependency of value on frequency of choice, frequency of choosing the globally maximizing alternative (A) would increase when participants apply a higher level of construal and assume a more psychologically distal perspective. Study 1 manipulated construal level through segmenting the sequence of trials into segments of different size, with bigger segments representing higher level of construal. In Study 2, participants played a practice game, and we manipulated the probability of playing the actual game. Both a higher level of construal and a lower probability of playing the actual game (higher distance) increased the number of A choices. These results suggest that a broad perspective that is induced by high level of construal or by psychological distancing may reduce sub‐optimal, meliorating choice.

“All‐or‐None” Versus “Most‐or‐Some” Options in Risky Choice: Effects of Domain and Handedness

Two methodological variants of Kahneman and Tversky's Asian disease scenario were investigated. One variant involved replacing the “all‐or‐none” outcome scenarios of the risky choice with “most‐or‐some” scenario outcomes, and the second variant involved replacing the negative domain of lives lost with a positive domain of jobs created. In addition, the effects of strength of handedness, a variable related to individual differences in risk perception, were examined. Results indicated that standard framing effects were obtained across both domains, with a decrease in risky choice under the gain domain. Scenario type also interacted with handedness, such that the all‐or‐none scenario yielded framing effects for consistent (strong)‐handers only, whereas the most‐or‐some scenario yielded framing effects for inconsistent (mixed)‐handers only (consistent‐handers are those who use the same hand exclusively for almost all activities). These results demonstrate that framing effects are strongly influenced by the presence versus absence of extreme/absolute outcomes and that individuals (in this case, decision makers with varying degrees of handedness strength) are differentially sensitive to different pieces of information.

The structure and validity of directional measures of appearance social comparison among emerging adults in China

We evaluated the structure and validity of the Upward Appearance Comparison Scale (UPACS) and Downward Appearance Comparison Scale (DACS) (O’Brien et al., 2009) in Chinese samples. In Study 1, principal component analysis on an initial sample (427 women, 123 men) and confirmatory factor analysis on another sample (447 women, 121 men) found that a 15-item, two component model had the best overall fit. Derived components had moderate correlations with most conceptually related measures and low correlations with less conceptually related indices. Study 2 participants (310 women, 201 men) completed the UPACS and DACS as well as measures of disordered eating, fatness concern, and negative affect; they were re-assessed one year later. Baseline UPACS scores predicted changes in disordered eating for women and fatness concerns for men, independent of initial disturbances, but DACS responses were not related to outcomes. Findings highlighted the potential utility of derived UPACS and DACS within a Chinese context.     

论元结构的焦点和重音关系对话语理解的影响

本研究采用韵律合适度判断和理解任务,通过两个实验探讨论元结构的焦点和重音之间的关系对话语理解的影响。实验通过操纵答句中的论元是否出现在问句中,变化问句的信息状态;通过操纵答句不同句子成份重读,变化答句的重读位置。实验结果发现:新论元负载焦点必须重读;重读论元将焦点投射到句子的高一级单元上,但动词必须重读;旧论元不负载焦点不必重读,但负载焦点的动词必须重读。     

The importance of choice in therapy: From the perspective of a,hopefully flexible,CBT practitioner

The main purpose of this paper is to present a personal account of my therapeutic journey and to show how my practice of CBT is informed not only by orientation-specific variables (e.g. emphases on 1) attitude; 2) perpetuation of disturbance as opposed to its acquisition; 3) specificity; 4) the development of client self-help skills; and 5) homework), but by more general, trans-theoretical variables (e.g. rooting therapy in the bonds, views, goals and tasks domains of the working alliance and dealing effectively with threats to this alliance). In doing so, I hope to show that when practised well CBT draws upon general principles that span different therapeutic approaches as well as on ideas specific to CBT.     

Influences on Career Choice Among Psychology Undergraduate Students: Role of Social Agents

The study explored factors that mediate the choice of psychology as a major subject by undergraduate students. Participants were a convenience sample of 368 students from two higher education institutions in Southern Africa (males =186, females =182, mean age = 22.35 years, SD=2.84 years). Data were collected using a survey that investigated social agents that are considered important in students' career choices. The data were analysed to explore differences by family and peer influences. The findings suggest that the students in the sample regarded social influences important in their choice of psychology as a major subject.     

Work-related counselling-a psychodynamic approach

Abstract

The paper sets out to stimulate interest in counsellors and therapists about the unconscious relationships which people form with their work, through describing and analysing what goes on in work-related counselling with a psychodynamic approach. The author draws on twenty-five years of experience to reflect on the changing nature of what was once termed ‘vocational guidance', and offers some short case studies, as examples of ways in which a person's world of work can become intertwined with their internal world in a confusing and disabling way. The core concepts and techniques which have evolved are identified and discussed; attention is directed particularly to the importance of the client's expectations, die effect of time limitation, the place of work in the whole life, and dealing with transference.     

Categorization behaviour in adults,adolescents, and attention-deficit/hyperactivity disorder adolescents: A comparative investigation

Although significant progress has been made with respect to our understanding of categorization and concept learning behaviour in adults, much less is known about how this key capacity plays out with respect to more restrictive populations. This is unfortunate because much may be revealed about the nature of concept learning by examining the limits exhibited by special populations. With this tenet in mind, in what follows, we investigated key aspects of concept learning in terms of the unexplored comparative performance of three populations—adults, adolescents, and adolescents with attention-deficit/hyperactivity disorder (ADHD). To do so, we employed a novel parainformative experimental task involving categorical stimuli with four objects defined over three dimensions. The learning difficulty ordering for these types of three-dimensional stimuli has proven robust and has been replicated by several researchers. Indeed, in our experiment, we observed the same concept learning ordering in adults and adolescents, but not in ADHD adolescents: For example, the latter group showed greatly impaired categorization performance on stimuli characterized by an “exclusive-or” rule. However, categorization performance on such type of stimuli indicated good reliability in discriminating between adolescents with and without ADHD (receiver-operating characteristic, ROC?=?.82). We accurately predicted and accounted for these results using generalized invariance structure theory (GIST; Vigo, 2013. The GIST of concepts. Cognition, 129, 138–162), which posits that organisms detect invariance patterns in stimuli that are necessary precursors to concept formation.     

Evolutionary policy contexts and policies in preparation for the twenty‐first century

The importance of preparing now for the next century is emphasized. The author's field and Kondratiev theories as a basis for long‐range policymaking over periods of dynamic, recon‐figurational change are briefly reviewed, and a number of assumptions relevant to this kind of policymaking are provided.. Equilibrium and nonequilibrium structures and thinking are contrasted. Limitations to control associated with limits to knowledge and knowability are discussed. The possibility is considered that continuation of present policies and practices may accelerate movement along a trajectory to nowhere. Problem solutions are considered within the context of what is meant by a civilized society, and some 15 characteristics of a civilized society are proposed. The theoretical basis for preparation for the Twenty‐First Century is advanced. Deficiencies in the present dominant politicoeconomic theories of Western Capitalistic Democracy and Marxism are discussed, and the need for a new set of “founding fathers” is proposed. The importance of developing and implementing a replacement theory of similar magnitude to present theories is emphasized, and the nature of this theory is briefly sketched. Some recommendations for guided paradigm change are offered.
