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.     

Empiricism,probability, and knowledge of arithmetic: A preliminary defense

The topic of this paper is our knowledge of the natural numbers, and in particular, our knowledge of the basic axioms for the natural numbers, namely the Peano axioms. The thesis defended in this paper is that knowledge of these axioms may be gained by recourse to judgments of probability. While considerations of probability have come to the forefront in recent epistemology, it seems safe to say that the thesis defended here is heterodox from the vantage point of traditional philosophy of mathematics. So this paper focuses on providing a preliminary defense of this thesis, in that it focuses on responding to several objections. Some of these objections are from the classical literature, such as Frege's concern about indiscernibility and circularity (Section 2.1), while other are more recent, such as Baker's concern about the unreliability of small samplings in the setting of arithmetic (Section 2.2). Another family of objections suggests that we simply do not have access to probability assignments in the setting of arithmetic, either due to issues related to the ω-rule (Section 3.1) or to the non-computability and non-continuity of probability assignments (Section 3.2). Articulating these objections and the responses to them involves developing some non-trivial results on probability assignments (Appendix A–Appendix C), such as a forcing argument to establish the existence of continuous probability assignments that may be computably approximated (Theorem 4 Appendix B). In the concluding section, two problems for future work are discussed: developing the source of arithmetical confirmation and responding to the probabilistic liar.     

认知主义与联结主义之比较

认知主义的研究定向和联结主义的研究定向是广义的现代认知心理学的两种主要研究范式。这两种研究范式都各有自己的研究内容和方法论,也取得了各自不同的成就,同时也存在各自不同的问题。通过对两种研究范式的比较,我们可以清楚地认识到二者的相互沟通和融合才是认知心理学未来发展的必然趋势。

A priori causal laws

Sober and Elgin defend the claim that there are a priori causal laws in biology. Lange and Rosenberg take issue with this on Humean grounds, among others. I will argue that Sober and Elgin don’t go far enough – there are a priori causal laws in many sciences. Furthermore, I will argue that this thesis is compatible with a Humean metaphysics and an empiricist epistemology.     

Assessing affective experience of in-situ environmental walk via wearable biosensors for evidence-based design

In environmental psychology research, the most commonly used methods are phenomenological interviews and psychometric scales. Recently, with the development of wearable bio-sensing devices, a new approach based on bio-sensing data is becoming possible. In this study, we examined the feasibility of using wearable biosensors to document affective experience during in-situ walk. An eight-channelled Procomp multi-bio-sensing devices (EKG, EEG, skin conductance, temperature, facial EMG, respiration) were used, in addition with a GPS tracker, to measure the in situ physiological affective responses to environmental stimuli. This pilot experiment revealed consistent results between bio-sensing measures and two traditional methods, i.e. phenomenological interviews and psychological Likert scale rating, which indicated that mobile bio-sensing could be a promising method in measuring in-situ affective responses to environmental stimuli as well as diagnosing potential environmental stressor. This new bio-sensory method, as exemplified in this paper, could help identifying negative stressful stimuli and providing evidence-based diagnosis to support design strategies.     

Estimating the probability and fidelity of memory

Research on memory may benefit from paradigms that permit graded characterization of memory performance, but a simple variance-based approach to the analysis of such graded data confounds two potential sources of error: the probability of memory and the fidelity of memory. Such data are more properly modeled by a mixture distribution, thereby permitting explicit estimation of both the probability and fidelity of memory. An expectation-maximization algorithm is presented for fitting such data to a mixture model, and Monte Carlo validation of this tool reveals circumstances under which it may be expected to be most effective. Limitations of the tool are outlined with respect to potential confounds in experiment design and interpretation of results. Finally, approaches to ameliorating such confounds are discussed. An R procedure for fitting response error data to mixture models may be downloaded from http://brm.psychonomic-journals.org/content/supplemental.     

Backward recognition failure: A case of retrieval success

Tulving and Wiseman (1975) have demonstrated that a systematic relationship exists between the recognition probability of recallable words and the overall level of recognition. However, this relationship has only been shown in the paradigms examining “forward” recognition failure, as defined by Rabinowitz, Mandler and Barsalou (1977). A reanalysis of their data shows that just such a systematic relationship exists in “backward” recognition failure experiments, and a model developed from the tenets of Fragmentation Theory is shown to predict this. A critical experiment which falsifies the dual-coding, dual-access model used by Rabinowitz et al. (1977) is also reported, thereby extending the generality of the Fragmentation Model.     

Attentional biases in social anxiety: an investigation using the inattentional blindness paradigm

One line of research has examined attentional bias as a potential maintenance factor in social anxiety using cognitive experiment paradigms. The present study sought to examine the utility of the inattentional blindness (IB) paradigm for assessing attentional bias in social anxiety. Unlike other existing paradigms such as the emotional Stroop or dot-probe tasks, the IB paradigm has the advantage of eliminating the individual's expectation and intention to search for social cues, which would reduce strategic or effortful responses. Two independent experiments were conducted using college students scoring high or low on the Fear of Negative Evaluation Scale. In both Experiments 1 and 2, participants were randomized to one of three IB experiment conditions, in which a positive face, a negative face, or a neutral item was unexpectedly presented, in the presence/absence of a bogus-speech threat. The overall pattern of our data suggests the presence of hypervigilant attentional processing in social anxiety. The IB paradigm appears to be a useful addition to existing experiment paradigms for investigating attentional bias in social anxiety and perhaps other psychopathology.

Web-based experiments controlled by JavaScript: An example from probability learning

JavaScript programs can be used to control Web experiments. This technique is illustrated by an experiment that tested the effects of advice on performance in the classic probability-learning paradigm. Previous research reported that people tested via the Web or in the lab tended to match the probabilities of their responses to the probabilities that those responses would be reinforced. The optimal strategy, however, is to consistently choose the more frequent event; probability matching produces sub-optimal performance. We investigated manipulations we reasoned should improve performance. A horse race scenario in which participants predicted the winner in each of a series of races between two horses was compared with an abstract scenario used previously. Ten groups of learners received different amounts of advice, including all combinations of (1) explicit instructions concerning the optimal strategy, (2) explicit instructions concerning a monetary sum to maximize, and (3) accurate information concerning the probabilities of events. The results showed minimal effects of horse race versus abstract scenario. Both advice concerning the optimal strategy and probability information contributed significantly to performance in the task. This paper includes a brief tutorial on JavaScript, explaining with simple examples how to assemble a browser-based experiment.     

Online webcam-based eye tracking in cognitive science: A first look

Online experimentation is emerging in many areas of cognitive psychology as a viable alternative or supplement to classical in-lab experimentation. While performance- and reaction-time-based paradigms are covered in recent studies, one instrument of cognitive psychology has not received much attention up to now: eye tracking. In this study, we used JavaScript-based eye tracking algorithms recently made available by Papoutsaki et al. (International Joint Conference on Artificial Intelligence, 2016) together with consumer-grade webcams to investigate the potential of online eye tracking to benefit from the common advantages of online data conduction. We compared three in-lab conducted tasks (fixation, pursuit, and free viewing) with online-acquired data to analyze the spatial precision in the first two, and replicability of well-known gazing patterns in the third task. Our results indicate that in-lab data exhibit an offset of about 172 px (15% of screen size, 3.94° visual angle) in the fixation task, while online data is slightly less accurate (18% of screen size, 207 px), and shows higher variance. The same results were found for the pursuit task with a constant offset during the stimulus movement (211 px in-lab, 216 px online). In the free-viewing task, we were able to replicate the high attention attribution to eyes (28.25%) compared to other key regions like the nose (9.71%) and mouth (4.00%). Overall, we found web technology-based eye tracking to be suitable for all three tasks and are confident that the required hard- and software will be improved continuously for even more sophisticated experimental paradigms in all of cognitive psychology.     

A meta-analysis of response-time tests of the sequential two-systems model of moral judgment

The (generalized) sequential two-system (“default interventionist”) model of utilitarian moral judgment predicts that utilitarian responses often arise from a system-two correction of system-one deontological intuitions. Response-time (RT) results that seem to support this model are usually explained by the fact that low-probability responses have longer RTs. Following earlier results, we predicted response probability from each subject’s tendency to make utilitarian responses (A, “Ability”) and each dilemma’s tendency to elicit deontological responses (D, “Difficulty”), estimated from a Rasch model. At the point where A = D, the two responses are equally likely, so probability effects cannot account for any RT differences between them. The sequential two-system model still predicts that many of the utilitarian responses made at this point will result from system-two corrections of system-one intuitions, hence should take longer. However, when A = D, RT for the two responses was the same, contradicting the sequential model. Here we report a meta-analysis of 26 data sets, which replicated the earlier results of no RT difference overall at the point where A = D. The data sets used three different kinds of moral judgment items, and the RT equality at the point where A = D held for all three. In addition, we found that RT increased with A–D. This result holds for subjects (characterized by Ability) but not for items (characterized by Difficulty). We explain the main features of this unanticipated effect, and of the main results, with a drift-diffusion model.     

Toward Unity in Psychology: The Experimental Synthesis of Behaviour

The current state of fragmentation of psychology is discussed in the context of Kuhn's paradigms. Schools of psychology are considered analogous to paradigms, although Kuhn would not think of psychology as a paradigmatic science. Schools gave origin to systems of psychology (neo-behaviourism, neo-psychoanalysis, dialectic-materialistic psychology, and humanistic psychology). A unifying paradigm, the experimental synthesis of behaviour, is presented as a programme. It is derived from the experimental analysis of behaviour. It is not an eclectic approach, but a new paradigm with the aim of unifying psychology as a science. Its main characteristics and advantages are discussed.     

Multiple levels of inquiry in cognitive science

Summary Gibsonian ecological psychology, symbolic information processing, and connectionist information processing are frequently construed as three competing paradigms or research traditions, each seeking dominance in experimental psychology and in cognitive science generally. There is an important element of truth in this perspective, and any adequate account of the development of experimental psychology over the past 30 years would have to examine seriously how the various conceptual frameworks, experimental endeavors, and social institutions have figured in this conflict. But the goal of this paper is not to characterize the historical dynamics within experimental psychology and cognitive science; rather, it is to consider what sorts of rapprochement is possible. Rapprochement, however, is not sought simply for its own sake or out of an a priori conviction that scientific enterprises should be unified. Spirited controversy between competing traditions is often an important component of progess (Laudan, 1977). Rapprochement has a purpose when alternative theoretical traditions have reached a point when each confronts serious shortcomings that can best be overcome by incorporating alternative perspectives. In this paper I try to show that this is the situation that exists in experimental psychology and cognitve science generally with respect to the three traditions enumerated above. I first explore how cognitive inquiry directed at internal procedures for processing information could benefit from a detailed study of the context of cognition, including insights provided by the Gibsonian tradition. Second, I examine the current controversy between symbolic and connectionist approaches and address the question of what contributions each offers to the other. Finally, I offer a framework in which multiple levels of inquiry in cognitve science can be related.     

BALDEY: A database of auditory lexical decisions

In an auditory lexical decision experiment, 5541 spoken content words and pseudowords were presented to 20 native speakers of Dutch. The words vary in phonological make-up and in number of syllables and stress pattern, and are further representative of the native Dutch vocabulary in that most are morphologically complex, comprising two stems or one stem plus derivational and inflectional suffixes, with inflections representing both regular and irregular paradigms; the pseudowords were matched in these respects to the real words. The BALDEY (“biggest auditory lexical decision experiment yet”) data file includes response times and accuracy rates, with for each item morphological information plus phonological and acoustic information derived from automatic phonemic segmentation of the stimuli. Two initial analyses illustrate how this data set can be used. First, we discuss several measures of the point at which a word has no further neighbours and compare the degree to which each measure predicts our lexical decision response outcomes. Second, we investigate how well four different measures of frequency of occurrence (from written corpora, spoken corpora, subtitles, and frequency ratings by 75 participants) predict the same outcomes. These analyses motivate general conclusions about the auditory lexical decision task. The (publicly available) BALDEY database lends itself to many further analyses.     

Affective empathy as core moral agency: psychopathy,autism and reason revisited

Empathy has become a common point of debate in moral psychology. Recent developments in psychiatry, neurosciences and social psychology have led to the revival of sentimentalism, and the ‘empathy thesis’ has suggested that affective empathy, in particular, is a necessary criterion of moral agency. The case of psychopaths – individuals incapable of affective empathy and moral agency, yet capable of rationality – has been utilised in support of this case. Critics, however, have been vocal. They have asserted that the case of autism proves the empathy thesis wrong; that psychopathy centres on rational rather than empathic limitations; that empathy is not relevant to many common normative behaviours; and that rationality is required when empathy fails. The present paper analyses these four criticisms. It will be claimed that they each face severe difficulties, and that moral agency ought to be approached via a multi-tier model, with affective empathy as a baseline.     

A note on accepting the null hypothesis: problems with respect to the mass-spring and pulse-step models of movement control

Models are sometimes developed on the premise that there are no differences between two or more conditions regardless of experimental manipulation. This article argues that unless a very sensitive experiment (or series of experiments) was conducted, such conclusions are often premature. Design and statistical factors such as alpha level, variability, sample size, and treatment effect are all determinants of the sensitivity of the experiment. It is sometimes the case that an experiment produces differences between means and yet the null hypothesis is not rejected because of high variability within experimental conditions or because too few subjects were used. Unless the probability of detecting a difference between groups is known, it would seem unwise to conclude that no difference exists. Judgment on the model should be suspended. Examples are taken from the mass-spring and pulse-step models fro voluntary movement control to illustrate the problem.
