Surviving without a Brain: A response to McMahan on Personal Identity

Abstract

In his Ethics of Killing: Problems at the Margins of Life, Jeff McMahan defends what he calls the embodied mind view of identity, and then puts forward several arguments in support of the view that physical continuity of the brain is crucial to our survival. He ultimately denies that psychological continuity is of any importance. His strategy is to recommend, by means of thought experiments, intuitions that support the importance of physical continuity of the brain and then argue against the plausibility of the notion of psychological continuity to which psychological theorists appeal. This paper is specifically concerned with the alleged importance of physical continuity to our survival. It responds to the positive and negative aspects of McMahan’s case by arguing that thought experiments that recommend the psychological view are far more compelling than he allows them to be and that psychological theorists can make do with a notion of psychological continuity that is immune to his criticisms.     

A set of semantic norms for German and Italian

The psychological community frequently investigates semantic norms of properties produced by native speakers after being presented concept words, and these norms are of great value for a wide variety of psychological experiments. This paper presents a new set of norms that includes a collection of properties from a production experiment for the German and the Italian languages. Stimuli consisted of 50 concrete objects taken from 10 different concept classes. The data comprise annotations of semantic relation types and several statistical measures, which facilitate the comparison of the two target languages.     

The equal division kernel: An equity approach to coalition formation and payoff distribution in N-person games

Most existing models of coalition formation and payoff distribution in groups rest upon normative considerations and are ambiguous in their predictions insofar as they do not determine which of several coalitions will most probably result. The paper sketches the basic features of a model derived from social psychological exchange-and equity-theory which predicts coalitions and payoff distributions for a variety of situations. The evaluation of the model by the results of several experiments indicates that it provides a reasonable starting point for further theoretical developments that are based empirical studies.     

Recent developments in the experimental investigation of the illusion of control. A meta‐analytic review

The present study analyzes recent developments in the experimental investigation of the illusion of control by using the methods of meta‐analysis. The aim of the study was to estimate the effect sizes associated with different factors thought to induce the illusion of control considering different conceptualizations of the phenomenon. The overall weighted mean effect size (D) was.62, with the 95% confidence interval about the mean.49 to.75. Generally, experiments tend to obtain moderate to large effect sizes, and the illusion of control is constantly present as an effect of several situational and psychological factors. Nevertheless, the large heterogeneity of the studies in terms of dependent measures suggests that the underlying phenomena can be of a different nature.     

Parenting Cognitions Associated with the Use of Psychological Control

Psychological control is a pattern of parenting that is intrusive and manipulative of children's thoughts, feelings, and attachment to parents. Although little is known about the determinants of psychological control, it has been linked to the psychological status of the parent. We hypothesized that several parenting cognitions reflecting personal concerns would be associated with the use of psychological control: low perceived control, sensitivity to hurt, and a disapproving attitude to negative emotion. We also examined moderating associations with child temperament and child gender. Participants were 198 mothers and fathers of 3- and 4-year-olds (106 boys, 92 girls; M age = 4.10 years, SD = 0.26). Parents completed self- and spouse-report measures of psychological control, rated their child's temperamental characteristics, and completed measures of parenting cognitions. Predictions were generally supported for two of the three cognitions. Sensitivity to hurt and disapproval of negative emotion were associated with more frequent reported use of psychological control. There were some moderating effects of child characteristics.     

Similarity, confusability, and the density hypothesis

Results from several letter- and digit-identification studies have been interpreted (Appelman & Mayzner, 1982; Krumhansl, 1982) as providing support for the hypothesis that psychological similarity is influenced by the local density of items in the stimulus space. This conclusion is questioned on the grounds that density was not directly manipulated in the studies, thus alternative explanations based on other stimulus characteristics cannot be excluded. In the present article six experiments are reported in which stimulus density was manipulated. In three experiments using similarity ratings and two using discrimination confusions, no effect of stimulus density was found. However, the identification counterpart of one of the discrimination studies did provide evidence of an effect of density on response probabilities. It is concluded that stimulus density can affect identification performance through its influence on the choice process implicit in any identification task, but is not an important determinant of psychological similarity.     

母亲心理控制与青少年问题性网络使用：非适应性认知的中介作用

本研究旨在考察母亲心理控制对青少年问题性网络使用（PIU）的直接和间接作用路径,以及这些路径是否受到性别的调节。以四所初级中学660名青少年为被试,要求其报告母亲的心理控制、非适应性网络认知以及问题性网络使用的情况。结果表明：（1）在控制了性别、年龄、家庭经济状况后,母亲心理控制对青少年PIU具有显著的正向预测作用;（2）非适应性认知在母亲心理控制与PIU之间具有部分中介作用;（3）母亲心理控制与PIU的直接关系（包括总效应和残余效应）以及间接关系（包括心理控制与非适应性认知的关系和非适应性认知与PIU的关系）均未受到性别的调节。研究结果说明母亲心理控制既直接影响青少年PIU,同时也通过非适应性认知产生间接影响,这些直接和间接路径在本研究中未表现出性别差异。     

Relational Desires and Empirical Evidence against Psychological Egoism

Abstract: Roughly, psychological egoism is the thesis that all of a person's intentional actions are ultimately self‐interested in some sense; psychological altruism is the thesis that some people's intentional actions are ultimately other‐regarding in some sense. C. Daniel Batson and other social psychologists have argued that there are experiments that provide support for a theory called the ‘empathy‐altruism hypothesis’, which entails the falsity of psychological egoism. However, several critics claim that there are egoistic explanations of the data that are still not ruled out. One of the most potent criticisms of Batson comes from Elliott Sober and David Sloan Wilson. I argue for two main theses in this paper: (1) we can improve on Sober and Wilson's conception of psychological egoism and altruism, and (2) this improvement shows that one of the strongest of Sober and Wilson's purportedly egoistic explanations is not tenable. A defense of these two theses goes some way toward defending Batson's claim that the evidence from social psychology provides sufficient reason to reject psychological egoism.     

Perception of surface curvature and direction of illumination from patterns of shading

Three experiments examine the perceptual salience of shading information for the visual specification of three-dimensional form. The observers in these experiments were required to estimate the surface curvature and direction of illumination depicted in computer-synthesized images of cylindrical surfaces, both with and without texture. The results indicate that the shininess of a surface enhances the perception of curvature, but has no effect on perceived direction of illumination; and that shading is generally less effective than texture for depicting surfaces in three dimensions. These and other findings are used to evaluate the psychological validity of several mathematical analyses of shading information that have recently been proposed in the literature.     

Modeling task switching without switching tasks: a short-term priming account of explicitly cued performance

Switch costs in task switching are commonly attributed to an executive control process of task-set reconfiguration, particularly in studies involving the explicit task-cuing procedure. The authors propose an alternative account of explicitly cued performance that is based on 2 mechanisms: priming of cue encoding from residual activation of cues in short-term memory and compound cue retrieval of responses from long-term memory. Their short-term priming account explains the repeated cue encoding benefit, switch cost, reduction in switch cost with preparation time, and other effects. The authors develop a mathematical model of their priming account and fit it to data from 3 experiments, demonstrating that a set of basic psychological processes can produce several effects--including putative switch costs--without switching tasks.     

Salient Volunteering Behavior Increases Monetary Risk‐taking

Research finds that engaging in prosocial behavior has many positive psychological outcomes (e.g., enhanced well‐being, optimism, perceived control, and a boost in self‐concept), and research on monetary risk‐taking reveals these psychological outcomes are associated with increased risk‐taking. Merging these findings, we propose that when people's volunteering behavior is made salient in their minds, they take more monetary risks. Making research participants’ volunteering behavior salient by having them recall an act of prior volunteering (studies 1 and 3), choosing whether to volunteer (study 2), or choosing one of two volunteering activities (study 4), four experiments (and a fifth reported in the Appendix S2) reveal increased risk‐taking across several monetary‐risk outcomes (incentive‐compatible gambles, allocation of a windfall gain, and a behavioral risk‐taking measure involving escalating risk). Lastly, when the decision maker attributes a decision to volunteer to an external source, the effect of salient volunteering on monetary risk‐taking attenuates.     

Wildcat World: Simulation programs for teaching basic concepts in psychological science

A series of computer programs is described that allows beginning psychology students to design, conduct, analyze, and interpret virtual (computer-simulated) psychological studies. This technique allows the instructor more control over the outcome of student experiments, increases the scope of experiments that can be done by students, decreases the amount of class time that must be devoted to conducting experiments, and eliminates concerns about student experimenters using human or animal subjects.     

Identity moderates the effects of Christmas displays on mood, self-esteem, and inclusion

In two experiments we examined the differential psychological consequences of being in the presence of a Christmas display on participants who did or did not celebrate Christmas (Study 1), or who identified as Christian, Buddhist, or Sikh (Study 2). Participants completed measures of psychological well-being in a cubicle that either did or did not contain a small Christmas display. Across several indicators of well-being, the display harmed non-celebrators and non-Christians, but enhanced well-being for celebrators and Christians. In Study 2, we found that the negative effect of the display on non-Christians was mediated by reduced feelings of inclusion. The results raise concerns about the ubiquitous presence of dominant cultural symbols (such as Christmas displays) in culturally diverse societies.     

The Relationship of Hardiness, Gender, and Stress to Health Outcomes in Adolescents

The present study examined the relationship between the hardiness components of commitment, control, and challenge, and the experience of physical and psychological symptoms in a sample of 150 (75 male, 75 female) adolescents. A measure of psychosocial stress was included to permit an examination of whether the hardiness components interact with stress in predicting health outcomes. Analyses revealed main effects of stress, gender, and the hardiness components of commitment and control for several of the health measures. More important was the finding of a consistent interaction of stress, gender, and hardiness for several of the health measures. Whereas low-stress males experienced few physical and psychological symptoms regardless of their levels of commitment and control, high-stress males experienced more problems when they were low rather than high in either commitment or control. The hardiness components did not interact with stress in the prediction of health outcomes among females.     

Painless computer-controlled experimentation

More Es might employ computers to control psychological experiments if computer languages suitable for experimental control were easier to learn. In fact, course author languages intended for writing instructional sequences offer many facilities desirable for experimental control. A particular language, CAN-4, is examined for its suitability, and its use in a concept learning experiment is illustrated.     

When do the stigmatized make attributions to discrimination occurring to the self and others? The roles of self-presentation and need for control

Two experiments examined how the goals of self-presentation and maintenance of control over one's outcomes influence women's tendencies to make or to avoid making attributions to discrimination. Demonstrating the importance of self-presentational goals, Experiment 1 showed that targets of discrimination were just as likely as similar others to make attributions to discrimination under private reporting conditions, but they were significantly less likely to do so under public reporting conditions. This experiment also provided initial evidence that need for personal control increases discrimination attributions. Experiment 2 demonstrated that targets' minimization of discrimination, observed in public reporting conditions, was eliminated when the need to reassert personal control was induced. Both experiments also demonstrated that failing to view events as discrimination has negative psychological costs.     

Does avoidance‐attachment style attenuate the benefits of being listened to?

We tested both Rogers's hypothesis that listening enables speakers to experience psychological safety and our hypothesis that the benefit of listening for psychological safety is attenuated by avoidance‐attachment style. We tested these hypotheses in six laboratory experiments, a field correlational study, and a scenario experiment. We meta‐analyzed the results of the laboratory experiments and found that listening increased psychological safety on average but that the variance between the experiments was also significant. The between experiment variance in the effect of listening manipulation on psychological safety exposes a methodological challenge in choosing a research paradigm of good‐versus‐normal listening, as opposed to normal‐versus‐poor listening. More importantly, we found, as expected and across all designs, that the higher the avoidance‐attachment style was, the lower the effect of listening on psychological safety. This finding has implications both for practice and for placing a theoretical boundary on Rogers's theory.     

SPLIT: A sound editor for a PDP-8 computer

SPLIT is a program that helps prepare sounds for use in psychological experiments. Analog signals are converted to digital form and stored on a disk in real time. Digital sound files can be viewed on an oscilloscope display and played back for on-line auditory inspection. Interactive commands allow the user to segment and combine sounds with precise temporal control.     

S.I.M.P.L.E. control and measurement of auditory events

A SIMPLE interactive programming language is shown to be useful for psychological research involving auditory stimuli and responses. It is helpful in recording spoken stimulus tapes with program control of event sequencing and timing; it can control on-line interactive auditory and bisensory experiments; and it can calibrate the stimulus durations and pause times for auditory events.
