Individual reactions to a multisensory immersive virtual environment: the impact of a wind farm on individuals

The aim of this study was to assess the impact of a wind farm on individuals by means of an audio-visual methodology that tried to simulate biologically plausible individual-environment interactions. To disentangle the effects of auditory and visual components on cognitive performances and subjective evaluations, unimodal (Audio or Video) and bimodal (Audio + Video) approaches were compared. Participants were assigned to three experimental conditions that reproduced a wind farm by means of an immersive virtual reality system: bimodal condition, reproducing scenarios with both acoustic and visual stimuli; unimodal visual condition, with only visual stimuli; unimodal auditory condition, with only auditory stimuli. While immersed in the virtual scenarios, participants performed tasks assessing verbal fluency, short-term verbal memory, backward counting, and distance estimations (egocentric: how far is the turbine from you?; allocentric: how far is the turbine from the target?). Afterwards, participants reported their degree of visual and noise annoyance. The results revealed that the presence of a visual scenario as compared to the only availability of auditory stimuli may exert a negative effect on resource-demanding cognitive tasks but a positive effect on perceived noise annoyance. This supports the idea that humans perceive the environment holistically and that auditory and visual features are processed in close interaction.     

Effect of circadian rhythms on retrieval-induced forgetting

This study investigated the effects of natural circadian rhythms on retrieval-induced forgetting (RIF; Anderson et al. in J Exp Psychol Learn Mem Cogn 20:1063–1087, 1994). Individuals tested at optimal times (i.e., morning persons tested in the morning and evening persons tested in the evening) showed a significantly greater RIF effect than individuals tested at non-optimal times (i.e., morning persons tested in the evening and evening persons tested in the morning). Thus, the limited quantity of resources available to allocate in the inhibitory activity during non-optimal times produced a significant decrement in RIF. These findings are compatible with the inhibitory account of RIF and with the notion of a resource-demanding process underlying this memory phenomenon.     

College Student Cheating: The Role of Motivation,Perceived Norms,Attitudes, and Knowledge of Institutional Policy

This study provides a comparative analysis of students' self-reported beliefs and behaviors related to six analogous pairs of conventional and digital forms of academic cheating. Results from an online survey of undergraduates at two universities (N = 1,305) suggest that students use conventional means more often than digital means to copy homework, collaborate when it is not permitted, and copy from others during an exam. However, engagement in digital plagiarism (cutting and pasting from the Internet) has surpassed conventional plagiarism. Students also reported using digital “cheat sheets” (i.e., notes stored in a digital device) to cheat on tests more often than conventional “cheat sheets.” Overall, 32% of students reported no cheating of any kind, 18.2% reported using only conventional methods, 4.2% reported using only digital methods, and 45.6% reported using both conventional and digital methods to cheat. “Digital only” cheaters were less likely than “conventional only” cheaters to report assignment cheating, but the former was more likely than the latter to report engagement in plagiarism. Students who cheated both conventionally and digitally were significantly different from the other three groups in terms of their self-reported engagement in all three types of cheating behavior. Students in this “both” group also had the lowest sense of moral responsibility to refrain from cheating and the greatest tendency to neutralize that responsibility. The scientific and educational implications of these findings are discussed in this study.     

Linguistic-pragmatic factors in interpreting disjunctions

' The connective or can be treated as an inclusive disjunction or else as an exclusive disjunction. Although researchers are aware of this distinction, few have examined the conditions under which each interpretation should be anticipated. Based on linguistic-pragmatic analyses, we assume that interpretations are initially inclusive before either (a) remaining so, or (b) becoming exclusive by way of an implicature (but not both). We point to a class of situations that ought to predispose disjunctions to inclusive interpretations and to situations that encourage exclusive interpretations. A disjunction's ultimate interpretation is based on its potential informativeness, where the interpretation of the disjunctive utterance having the smallest number of true conditions is considered most informative. Our investigation leads to five experiments employing arbitrary materials. Among the problems expected to encourage inclusive interpretations are those that present disjunctions in the antecedents of conditionals and in question forms. The best candidates to produce implicatures are those disjunctions that underdetermine an expected conjunctive conclusion, although other disjunctive utterances that are more informative as exclusive are discussed and tested.     

The role of attachment to God in secular and religious/spiritual ways of coping with a serious disease

This study investigated the role of security in one's attachment to God in relation to both secular and religious/spiritual ways of coping with a serious illness. The main objective was to test whether attachment to God and type of disease were related to secular coping strategies, when controlling for the effects of religious/spiritual coping. Study participants (N = 105) had been diagnosed either with cancer (i.e., an acute disease) and were under chemotherapy/awaiting surgery or with renal impairment (i.e., a chronic disease) and were attending dialysis. Results showed that secure attachment to God was uniquely related to fighting spirit, whereas insecure attachment to God was uniquely linked to hopelessness, suggesting that security, unlike insecurity, in one's attachment to God may impact favourably on adjustment to the disease. The only coping strategy related to type of disease was cognitive avoidance, which was linked to chronic disease.     

Operating on Functions with Variable Domains

The sum, difference, product and quotient of two functions with different domains are usually defined only on their common domain. This paper extends these definitions so that the sum and other operations are essentially defined anywhere that at least one of the components is defined. This idea is applied to propositions and events, expressed as indicator functions, to define conditional propositions and conditional events as three-valued indicator functions that are undefined when their condition is false. Extended operations of and, or, not and conditioning are then defined on these conditional events with variable conditions. The probabilities of the disjunction (or) and of the conjunction (and) of two conditionals are expressed in terms of the conditional probabilities of the component conditionals. In a special case, these are shown to be weighted averages of the component conditional probabilities where the weights are the relative probabilities of the various conditions. Next, conditional random variables are defined to be random variables X whose domain has been restricted by a condition on a second random variable Y. The extended sum, difference, product and conditioning operations on functions are then applied to these conditional random variables. The expectation of a random variable and the conditional expectation of a conditional random variable are recounted. Theorem 1 generalizes the standard result that the conditional expectation of the sum of two conditional random variables with disjoint and exhaustive conditions is a weighted sum of the conditional expectations of the component conditional random variables. Because of the extended operations, the theorem is true for arbitrary conditions. Theorem 2 gives a formula for the expectation of the product of two conditional random variables. After the definition of independence of two random variables is extended to accommodate the extended operations, it is applied to the formula of Theorem 2 to simplify the expectation of a product of conditional random variables. Two examples end the paper. The first concerns a work force of n workers of different output levels and work shifts. The second example involves two radars with overlapping surveillance regions and different detection error rates. One radar's error rate is assumed to be sensitive to fog and the other radar's error rate is assumed to be sensitive to air traffic density. The combined error rate over the combined surveillance region given heavy fog and moderate air traffic is computed.     

Alienation: its impact on adolescents from stable environments

This research examined the levels of alienation among adolescents from traditional and nontraditional backgrounds to determine whether family variables (religious affiliation or religious commitment) and economic factors were related to levels of alienation. Students (N = 1,064) from Grades 10, 11, and 12 at a large racially balanced urban high school and from Grades 7, 8, and 9 at one feeder junior high school in the Midwest were surveyed with the Dean Alienation Scale. The findings indicated that adolescents from traditional two-parent families with a strong religious commitment were more alienated than their peers. In addition, alienation was directly related to the economic status of the adolescent's parents and to the grade level of the adolescent.     

Adolescence: a growth period conductive to alienation

This paper clarifies the relationship of alienation to the period of adolescence by developing a portrait of the alienated and the at-risk adolescent. Current research on adolescent alienation follows two converging themes, the socio-psychological, where deviant behavior is viewed as evidence of adolescent estrangement from self and society, and the sociological, where alienation is divided into a series of dimensions for empirical assessment. These two perspectives converge to describe the alienated adolescent. The alienated adolescent is disruptive, rebukes authority, drops out of school or becomes a passive participant, is prone to suicide, abuses drugs and alcohol, and rejects the norms established by family, school, and society in general. Adolescence is a high-risk period wherein the adolescent experiences multiple environments which exacerbates higher levels of alienation. These environments include disorganized or disruptive families, schools that encourage students to become passive participants in the learning process, and a high-pressured pace of life. To lessen the at-risk nature of adolescents toward alienation, society can take steps to humanize their environment. These steps include the intergenerational integration of adolescents, their assimilation into responsible societal activities, providing them with a sense of meaning, and enfranchisement into the decision-making process.     

Prejudice in person memory: Self‐threat biases memories of stigmatized group members

The present research investigated whether self‐threat biases memory via retrieval‐induced forgetting. Results show that people under self‐threat whose goal is to restore their self‐worth by making prejudicial judgments that deprecate others are more likely to exhibit an enhanced RIF effect for positive items and a reduced RIF for negative items ascribed to a stereotyped target (i.e., homosexual). Overall, the present findings are consistent with the view that motivation can affect the magnitude of RIF effects in person memory and that, in turn, they can serve as mechanisms for justifying desired conclusions.     

Representationalism, peripheral awareness, and the transparency of experience

It is often said that some kind of peripheral (or inattentional) conscious awareness accompanies our focal (attentional) consciousness. I agree that this is often the case, but clarity is needed on several fronts. In this paper, I lay out four distinct theses on peripheral awareness and show that three of them are true. However, I then argue that a fourth thesis, commonly associated with the so-called "self-representational approach to consciousness," is false. The claim here is that we have outer focal consciousness accompanied often (or even always) by inner peripheral (self-)awareness. My criticisms stem from both methodological and phenomenological considerations. In doing so, I offer a diagnosis as to why the fourth thesis has seemed true to so many and also show how the so-called "transparency of experience," frequently invoked by representationalists, is importantly relevant to my diagnosis. Finally, I respond to several objections and to further attempts to show that thesis four is true. What emerges is that if one wishes to hold that some form of self-awareness accompanies all outer-directed conscious states, one is better off holding that such self-awareness is itself unconscious, as is held for example by standard higher-order theories of consciousness.
