‘Philosophy is its own time comprehended in thought’

So much philosophy is so unavoidably guided by intuitions, and such intuitions are so formed by examples, and such examples must of necessity present so cropped and abstract a picture of an instance or event or decision, that, left to its traditional methods, philosophy might be ill-equipped on its own to answer a question about the true content of an historical ideal like ``autonomy', or authenticity or ``leading a free life'. One needs to bring so many factors into play at once that one non-traditional but more promising path might be through reflection on the modern novel—or modern drama or poetry or film or even modern painting.     

The effects of magnitude and quality of reinforcement on choice responding during play activities

Three boys with autism participated in a study of the effects of magnitude and quality of reinforcement on choice responding. Two concurrent response alternatives were arranged: (a) to play in an area where a peer or sibling was located, or (b) to play in an area where there was no peer or sibling. During one condition, the magnitude (i.e., duration of access to toys) or quality (level of preference) of reinforcement provided for both responses was equal. During the other condition, the magnitude or quality of reinforcement was relatively greater for choosing the play area where the peer or sibling was located than the area where the peer or sibling was not located. Results showed that after repeated exposure to the unequal magnitude or quality condition, the participant increasingly allocated his responses to the play area where the peer or sibling was located. For 2 participants, this pattern of responding was maintained in the subsequent equal magnitude or quality condition. Overall, the analysis suggests that the dimensions of magnitude and quality of reinforcement can be arranged to influence choice responding in favor of playing near a peer or sibling rather than playing alone.     

Chronic psychosocial factors and acute physiological responses to laboratory-induced stress in healthy populations: a quantitative review of 30 years of investigations

This meta-analysis included 729 studies from 161 articles investigating how acute stress responsivity (including stress reactivity and recovery of hypothalamic-pituitary-adrenal [HPA] axis, autonomic, and cardiovascular systems) changes with various chronic psychosocial exposures (job stress; general life stress; depression or hopelessness; anxiety, neuroticism, or negative affect; hostility, aggression, or Type-A behavior; fatigue, burnout, or exhaustion; positive psychological states or traits) in healthy populations. In either the overall meta-analysis or the methodologically strong subanalysis, positive psychological states or traits were associated with reduced HPA reactivity. Hostility, aggression, or Type-A behavior was associated with increased cardiovascular (heart rate or blood pressure) reactivity, whereas anxiety, neuroticism, or negative affect was associated with decreased cardiovascular reactivity. General life stress and anxiety, neuroticism, or negative affect were associated with poorer cardiovascular recovery. However, regarding the sympathetic nervous system and parasympathetic nervous system, there were no associations between the chronic psychosocial factors and stress reactivity or recovery. The results largely reflect an integrated stress response pattern of hypo- or hyperactivity depending on the specific nature of the psychosocial background.     

Delay of gratification in children: The effects of training under fixed,decreasing and increasing delay of reward

The effect of fixed, gradually decreasing, or increasing delay of reward in discimination learning on later delay of gratification was investigated. In discrimination training, employing a correction procedure, a candy reward was delivered either after 0, 10, 20, 40 or 60 sec fixed delay; or after 60 sec in the first block of trials and decreased in successive block; or reward was immediate in the first block of trials and delay was gradually increased to 60 sec. In the delay of gratification tests, subjects could press a button immediately to receive a small reward (one candy or a cheap toy) or delay pressing and receive an increasingly larger reward (more candy or a better toy).Learning was not significantly affected by either fixed or decreasing delays. Increasing delays resulted in faster learning than decreasing delays. The increasing delay group demonstrated superior delay of gratification on both tests. Fixed delay groups did not differ significantly among themselves, nor from the decreasing delay group. The effectiveness of exposure to increasing delays in facilitating delay of gratification was interpreted as due to either the acquisition of coping responses or the extinction of frustration.     

Reasons given by UK churchgoers for their stance on evolution

A sample of 661 churchgoers from a range of Christian denominations in the United Kingdom was asked about Darwinian evolution (defined as the common origin of all species, including humans). Respondents were categorised as those who accepted the idea, those who rejected it, and those who were unsure or neutral. People in each category were given a number of statements that related to reasons why they might have held their particular stance, and responses were used to create summated rating scales. Reasons for accepting or rejecting evolution could be classified as broadly relating to the theory itself or to the religious consequences of the theory. Accepters saw the theory as rational and attractive, and one that allowed a role for God in shaping evolution. Rejecters saw the theory as unsupported by evidence and one that denied a role for God and/or contradicted Scripture. Those unsure or neutral seemed to be so because they lacked sufficient knowledge about evolution or the Bible, and/or because they were disinterested. Predicting which reasons were likely to be chosen by an individual was difficult, though there were significance differences in some cases between denominations and between those with or without education in biology or science.     

Teasing,rejection, and violence: Case studies of the school shootings

Media commentators have suggested that recent school shootings were precipitated by social rejection, but no empirical research has examined this claim. Case studies were conducted of 15 school shootings between 1995 and 2001 to examine the possible role of social rejection in school violence. Acute or chronic rejection—in the form of ostracism, bullying, and/or romantic rejection—was present in all but two of the incidents. In addition, the shooters tended to be characterized by one or more of three other risk factors—an interest in firearms or bombs, a fascination with death or Satanism, or psychological problems involving depression, impulse control, or sadistic tendencies. Implications for understanding and preventing school violence are discussed. Aggr. Behav. 29:202–214, 2003. © 2003 Wiley‐Liss, Inc.     

Familiarity decisions for faces presented to the left and right cerebral hemispheres

Right-handed subjects were asked to decide whether or not faces presented briefly in the RVF or in the LVF were familiar (familiar faces were those of famous people). This task avoids the need for extensive semantic processing or temporary storage involved in conventional naming or identification tasks, and thus eliminates the contribution of such factors to any observed asymmetry. The resulting finding of faster reaction times to LVF faces, with no overall visual hemifield difference in error rates, is taken to indicate a right-hemisphere superiority either in the processes used to construct facial representations or in the accessing of face recognition units, or both.     

A portable biofeedback device for autonomic responses

The design of a versatile and programmable transducer amplifier device with analogue display for self-monitoring of autonomic responses is described. The design features low cost, portability, and flexibility across direct-current transducer options (e.g., photoplethysmograph or thermistor). The device can be used for the visual or auditory display of continuous blood volume pulse or temperature measures where the relative amplitude or pulse rate is of concern. Auditory or visual biofeedback may be provided via the choice of a stacked bar-graph display or piezoelectric buzzer. A common circuit design to allow programming options for the estimation of heart rate, inter-beat interval, or pulse duration is provided.     

Comprehension of "absence" by an African Grey parrot: Learning with respect to questions of same/different

An African Grey parrot, Alex, learned to report on the absence or presence of similarity and difference between two objects. Alex was shown pairs of objects that were (a) totally dissimilar, (b) identical, or (c) similar or different with respect to one of three attributes (color, shape, or material). In the first two cases, he responded to the respective queries of “What's same?” or “What's different?” with the vocalization “none,” and in the third case he responded with the appropriate category label (“color,” “shape,” or “mah-mah” [matter]). His accuracy was 80.9% to 83.9% for pairs of familiar objects not used in training and 72.5% to 78.4% for pairs whose colors, shapes, and materials were unfamiliar. The data provide evidence that this parrot's abilities are comparable to those of mammals that have been trained to report on the presence or absence of objects or features of objects.     

Accessing stored information about familiar people

Summary Two experiments investigating access to occupations and names of familiar people are reported, in which the response requirements of occupation and name-categorization tasks were made equivalent. In Experiment 1 matching tasks were used, in which subjects were required to determine whether simultaneously presented pairs of faces, surnames, or full names were those of people with the same or different occupations (politician or nonpolitician) or with same or different first names (Michael or David). Experiment 2 required binary classification of individual faces or surnames in terms of the bearer's occupation (politician or nonpolitician) or first name (Michael or David). In both experiments responses to faces were faster in tasks involving access to occupations than in tasks involving access to first names, whereas for surnames there was no difference in reaction times between occupations and first names in matching or classification tasks. These findings are consistent with the idea that identity-specific semantic codes and name codes are accessed sequentially from faces, but in parallel from written names.

Age constraints on first versus second language acquisition: evidence for linguistic plasticity and epigenesis

Does age constrain the outcome of all language acquisition equally regardless of whether the language is a first or second one? To test this hypothesis, the English grammatical abilities of deaf and hearing adults who either did or did not have linguistic experience (spoken or signed) during early childhood were investigated with two tasks, timed grammatical judgement and untimed sentence to picture matching. Findings showed that adults who acquired a language in early life performed at near-native levels on a second language regardless of whether they were hearing or deaf or whether the early language was spoken or signed. By contrast, deaf adults who experienced little or no accessible language in early life performed poorly. These results indicate that the onset of language acquisition in early human development dramatically alters the capacity to learn language throughout life, independent of the sensory-motor form of the early experience.     

Can public virtues be global?

ABSTRACT

An important issue within the field of global ethics is the extent or scope of moral obligation or duties. Cosmopolitanism argues that we have duties to all human beings by virtue of some common property. Communitarian ethics argue that one's scope of obligation is circumscribed by one's community or some other defining property. Public virtues, understood to be either a property that communities possess to function well or a moral excellence constitutive of that community, offer an interesting challenge to this binary by positing moral goods or excellences that are constitutive of a community yet global in application. Virtues such as tolerance, charity, moderation, or benevolence might be examples of such goods or excellences endorsed by a community but applied to individuals who are not members of the community, or, as in the case of environmental ethics, even to entities that are not moral agents. Unlike cosmopolitan ethics, the scope of the obligation does not depend on identifying universal properties, such as rationality, human dignity, or utility, but could be defined entirely by and within a community.

Conceptualizing Coping: Optimism as a Case Study

Coping involves any effort to deal with difficult or challenging situations, and coping strategies vary, often depending on individual differences and situational circumstances. Research has typically characterized coping as either involving problem‐focused or emotion‐focused strategies, or sometimes approach or avoidance strategies. The current review suggests that a more useful distinction would be found in crossed dimensions, such as problem‐focused approach or avoidance, or emotion‐focused approach or avoidance. For example, the individual difference of dispositional optimism has been found to be positively associated with approach coping strategies seeking to solve or control either problems or emotions, depending on the type of stressor. Although widely used, current coping scales may contribute to a skewed view of coping strategies and may not adequately depict coping dimensions. The current review calls for revisions of current scales or creation of new and better scales.     

Resistance to continuous delay of reinforcement or extinction following partial delay or partial reinforcement in acquisition: A direct comparison

Rats received either partial reward (PR) or partial delay (PD) in acquisition with one, two, or three delay or nonreward trials followed by an immediately rewarded trial or one delay or nonreward trial followed by an immediately rewarded trial. These four groups were then split in half and given either continuous delay or continuous nonreward (extinction) in a “response persistence” phase. In addition, two continuously reinforced groups, one experiencing continuous delay, and the other experiencing extinction were included. The results showed that response persistence was greater when PD groups were given continuous delay rather than extinction, but the opposite was true for PR groups. The “length” (1, 2, or 3 versus 1 nonreward or delay trial) also transferred to the response persistence phase with the length 1, 2, and 3 conditions being more persistent than the 1 length conditions. The results were discussed with respect to theoretical notions of response persistence.     

Community Violence as It Affects Child Development: Issues of Definition

The state of the art of definition of community violence as it relates to child development was examined in terms of the definitions used in 23 empirical studies. In all cases community violence was defined in terms of what were assumed to be measurements obtained as linear combinations of a priori numerical weighting of responses to questions--asked either of a child or of the parent of a child--about experiencing and/or witnessing and/or hearing about instances of violence. Thus, the definitions can be seen to represent the perspectives of 2 kinds of observers--the child or the child's parent--and 3 levels of closeness to violence--experiencing, witnessing, or hearing about violence. Combining these perspectives and levels, the following 8 different definitions could be seen to be used in the practice of 1 or more of the 23 empirical studies: Child Self-Report (perception) of either (1) experiencing, or (2) witnessing, or (3) experiencing and witnessing, and hearing about violence; or Parent Report (perception) of the Child (4) experiencing, or (5) witnessing, or (6) experiencing and witnessing and hearing about violence, or (7) = (1) + (4), or (8) = (3) + (6). In almost all the examples of research definitions it was assumed implicitly and without test of the assumption that different violent events were interchangeable, and usually it was assumed (again without test) that the magnitudes of different violence events were equal. Usually, an unstated theory of stress appeared to guide the measurement definition, but in one study definitions were developed and tested in terms of a clearly-stated theory of learning. It was concluded that definition of community violence is a measurement problem; that very likely it is multidimensional; that it could be more nearly solved if better attention were given to specifying it in terms of theory that can be put to test and by attending to basic assumptions and principles of measurement.     

Social Costs of Smoking: Effects of Tobacco Smoke on Hostile Behavior1

Male and female undergraduates interacted with a same-sex experimenter and a same-sex assistant of the experimenter. Either the experimenter or the assistant smoked. Subjects were provoked or not provoked by the experimenter and then smoked. Subjects were provoked or not provided by the experimenter and then provided with an opportunity to treat him or her in a hostile manner. Additionally, subjects were classified as smokers or nonsmokers and as supporting or opposing smoking in public places. Tobacco smoke was found to facilitate hostile behavior whether or not subjects were independently annoyed and whether or not it originated from the annoyer or a bystander. No sex differences were observed in this effect. Also, no appreciable difference was observed in the hostile behavior of smokers and nonsmokers. Persons opposed to public smoking reacted more strongly to the provocation than persons supportive of public smoking, but this effect was independent of the presence or absence of smoke.     

Effects of causal belief for prior success or failure on preferences to delay gratification in task contingent versus task noncontingent conditions1

This study investigated how causal belief for prior success or failure affected preferences to delay gratifications in task contingent versus task noncontingent conditions. Success or failure on the Treatment Task and belief about the outcome were experimentally induced to lead fourth-and fifth-grade pupils to perceive task performance as resulting from one of four factors (Ability, Task Difficulty, Effort, or Luck). Thereafter, each subject chose between smaller, noncontingent rewards and delayed, larger rewards that were contingent on waiting only or on successful performance on tasks which varied in similarity to the initial task. As predicted, preferences to delay were not differentially affected by success or failure when subjects believed unstable factors of effort or luck caused the outcome. However, delay was affected by prior success or failure when the belief was that the outcome resulted from stable factors of ability or task difficulty, with subjects delaying more after success than following failure. Furthermore, the outcome predicted delay on tasks identical or similar to the Treatment Task whereas belief about causality predicted delay on the Different Task. Delay was greater by subjects with ability or effort inductions than by subjects with a luck induction.
