Individual Responsibility for Climate Change

As we become more aware of the potential causes and consequences of climate change we are left wondering: who is responsible? Climate change has the potential to harm large portions of the global population and, arguably, is already doing so. Further, climate change is argued to be human‐caused. If this is true, then it seems to be the case that we can analyze climate change in terms of responsibility. I argue that we can approach environmental harms, such as climate change, through a theory of collective responsibility. I propose an account of reductive collective responsibility that can apply to the unstructured collective causing climate change and determine what we are each individually morally responsible for. To avoid the critiques of reductive collective responsibility for large unstructured harms, I propose we separate the determination of membership and eligibility for responsibility from the attribution of responsibility. Through this method, I can speak to the individual responsibility of each member who contributes to climate change without holding them responsible for that which is outside their control.     

The Influence of Hope on the Relationship Between Racial Discrimination and Depressive Symptoms

This study investigated how hope influences the relationship between discrimination and depressive symptoms. Results from participants' (N = 318) responses suggest that increased levels of hope were directly related to decreased levels of depressive symptoms. However, increased levels of hope were also related to a stronger relationship between discrimination and depressive symptoms. Este estudio investigó cómo la esperanza influye en la relación entre discriminación y síntomas depresivos. Los resultados obtenidos a partir de las respuestas de los participantes (N = 318) sugieren que unos niveles más elevados de esperanza estuvieron directamente relacionados con unos niveles más bajos de síntomas depresivos. Sin embargo, los niveles superiores de esperanza también estuvieron relacionados con una relación más fuerte entre discriminación y síntomas depresivos.     

Is a Worried Citizen a Good Citizen? Emotions,Political Information Seeking,and Learning via the Internet

In this study we explore the mediating role of emotions in the process of becoming a politically informed citizen. Contrary to previous studies, we expect that anger and anxiety will have much different effects on this process. We suspect the role of anxiety is somewhat unique even among negative emotions as mediator of the causal effect of political threats on information seeking and learning. In addition, we speculate that anxiety should improve the quality of information seeking, not just its quantity. In one experiment, we induce emotions directly and find that while anger, enthusiasm, and anxiety can lead people to claim they will pay attention to the campaign, anger actually depresses total information seeking. In a second experiment, we examine the impact of realistic political threats and find that exposure triggers several emotions but that only anxiety boosts information seeking and learning.     

The Philosophical Roots of Ernst Mach's Economy of Thought

A full appreciation for Ernst Mach's doctrine of the economy of thought must takeaccount of his direct realism about particulars (elements) and his anti-realism aboutspace-time laws as economical constructions. After a review of thought economy,its critics and some contemporary forms, the paper turns to the philosophical rootsof Mach's doctrine. Mach claimed that the simplest, most parsimonious theorieseconomized memory and effort by using abstract concepts and laws instead ofattending to the details of each individual event or experiment. For Mach, theindividual case never truly repeated in all of its uniqueness, nor was all of theindividual detail of a physical element adequately captured in abstract laws andschemata, however necessary these were for the pursuit of science. As can beshown from specific passages, some already published, some not, Mach's elementsincluded physical qualia in nature similar to Russell's unsensed sensibilia, whichexisted even where there were no conscious observers. An argument will be presentedto make the case that Mach believed in the mind-independent elements from the 1870son, while other aspects of his thought evolved over time; I have thus dated the referencesto reflect this historical progression. I concentrate on Mach's ontology, as it bears oneconomy of thought, not his epistemology per se, which might well have been restrictedto observable elements/ sensations. After his own conversion to neutral monism, in the1920s, Bertrand Russell echoed Mach's call for a `future science' capable of handlingthe `intrinsic character' of qualitative data directly without the excessive abstraction ofphysics.     

Does the covert nature of caring prohibit the development of effective services for young carers?

Almost 3 million children in the UK live in households where at least one family member is affected by chronic illness or disability. A proportion of these children will be young carers. This paper begins with a brief review of the literature relating to young carers. Particular attention is paid to the adoption of a caring role, the'hidden' nature of caring including young people'sreluctance to discuss their caring, the impact of caring on education, and the location and type of services provided.The findings of a small-scale study carried out in Scotland are presented in order to highlight some of the issues raised in the literature. Discussion focuses on the implications for the field of guidance and counselling.     

Where Have All the Children Gone? Movement from Child to Adult Mental Health Systems

The mental health histories of the 448 children 15 and 16 years of age who were admitted to state-operated children's psychiatric inpatient services in New York during 1982 were reviewed for the 11 year period through April 1993, Thirty-three percent were served as adults (after age 18) in the state-operated adult civil mental health system; 42% of these individuals were still receiving services at the end of the period. 113 of the 146 individuals served as adults were served only in the civil system. Thirteen percent of the cohort received some of their mental health services as adults in the state-operated adult forensic mental health system due to criminal law involvement. This includes nine percent who received mental health services while they were inmates in state prisons. Twenty four of the 57 forensic clients received services as adults only in the forensic system. Diagnostic, demographic, and service history characteristics of the groups were compared to foster an early understanding of policy and programmatic issues related to movement from the child mental health system to the adult system. Baseline (1982) information was used to identify predictors of later service utilization.     

Discriminations among perceptual and symbolic stimuli

This research compares the time required for perceptual discriminations among pairs of physically present objects (circles) with the time required to discriminate pairs of symbols Inonsense syllables) that subjects learned to associate uniquely with each of the circles. Four experiments show very large differences between symbolic and perceptual discriminations. Discrimination times for the perceptual stimuli declined systematically as their size ratio increased, but discriminations among the associated nonsense syllables showed only a strictly ordinal effect of position in the series. Discriminations among the symbolic stimuli showed a large semantic congruity effect, but the perceptual stimuli showed none. The research does not replicate previous results showing similarities between perceptual and symbolic processing suggestive of image processing. We conclude that in the symbolic task subjects use only ordinal information rather than images or analog representations of the associated circles. We propose that perceptual discriminations show a semantic congruity effect only when they are processed as if the perceptual stimuli were symbolic.     

The perception of verticality and the frame of reference of the visual tilt aftereffect

Previous research has suggested that the visual tilt aftereffect operates according to a gravitational frame of reference. Three experiments were conducted to test this conclusion further. In each experiment, observers (with head upright) adjusted an illuminated bar to apparent vertical following various adaptation conditions. In Experiment 1, observers were given clear visual cues for objective vertical while adjusting the bar. In Experiment 2, they were not given visual cues for vertical. The adaptation conditions in Experiments 1 and 2 consisted of various combinations of head and stimulus tilt. Experiment 3 investigated the effects of head tilt alone. The results indicated that the tilt aftereffect follows a retinal frame of reference under some conditions (Experiment 1) and appears to follow a gravitational frame under others (Experiment 2). These results can be predicted by a simple model involving two factors, a purely visual aftereffect that follows a retinal frame and an extravisual aftereffect that appears to follow a gravitational frame.     

Assessing relations between imagery and perception

Direct comparisons between perceptual performance and reports made under imagery instructions are uninterpretable except in cases where (a) the perceptual phenomenon is well understood and (b) experimental constraints are sufficient to establish imagery causally in the effect. Neither condition seems to be satisfied in Finke and Kurtzman's article. Furthermore, if imagery is an internal medium conceived in introspective terms, the second condition can never be met because the medium is not accessible to operational definition. Perhaps the basic problem with this research is that the instructions used to create conditions in imagery experiments do not qualify as operational definitions. Reports of successful compliance with imagery instructions are logically equivalent to introspective reports.     

The effects of perceived similarity upon the use of reward and punishment

Subjects were led to perceive a trainee as either similar or dissimilar to themselves. During subsequent influence trials, subjects attempted to assess the causes of the trainee's performance and to employ rewards, punishments, or manipulations of the trainee's environment to optimize her performance. It was predicted that subjects would perceive the performance of dissimilar trainees as caused more by the dispositional factor of motivation than the performance of similar trainees, and that dissimilar trainees would thus be rewarded more upon success as well as punished more upon failure. The hypotheses were supported, and a model of reward-punishment behavior and attribution is discussed.
