Differences in incidental and intentional learning of sensorimotor sequences as revealed by event-related brain potentials.

The present study investigated differences in sequential learning between subjects who were or were not informed of the presence of a repeating sequence (intentional or incidental group, respectively). Subjects had to learn a 16-letter-long repeating sequence that was irregularly disrupted by deviating stimuli. Reaction times indicated that both groups learned the sequential regularities. Intentional learners showed a larger learning effect. Event-related brain potentials (ERPs) recorded during performance of the task showed a reliably enhanced amplitude for the N2b- and P3b-components for deviant letters for intentional learners, but not for incidental learners. These results are discussed in the context of models proposing that different neural structures are involved in implicit and explicit serial learning.

Alcohol concentration and the ability to form intent.

The ability to form intent to commit a particular act is often a significant issue in criminal litigation. Often, a complicating factor in the resolution of this issue is the presence of ethanol and drugs in the individual whose motives are to be ascertained. To determine whether an intoxicating blood ethanol concentration (BAC) in the absence of other information is sufficient to establish intent, we reviewed cases investigated by the Office of the Chief Medical Examiner, State of Maryland over a two-year period. Specifically, we identified cases of suicide with a suicide note, the presence of ethanol and the absence of other psychoactive drugs. The BACs ranged from 0.01 to 0.37 g/dL. The average BAC was 0.14 g/dL and the median BAC was 0.13 g/dL. Twenty-five of the 37 cases had a BAC greater than 0.08 g/dL. We conclude that a BAC alone is not sufficient to determine the capability of an individual to form intent to commit a particular act.

Identifying stalking: the relevance of intent in commonsense reasoning.

One method of distinguishing stalking from law-abiding behavior is to determine whether the accused intended to cause fear or harm to the target. However, this distinction may not capture community concerns regarding intrusive or harassing behavior. The present research examines the effect of intent, persistence, relationship, and consequences on community perceptions of stalking. Responses of 1,080 members of the community to a series of scenarios indicated that the presence of explicit evidence of intent was not the only way stalking behavior was identified. Behavior was also identified as stalking as a greater degree of persistence was depicted. Females more often than males perceived the behavior as stalking and inferred intent to cause fear or harm. Most participants who identified the behavior as stalking also indicated that it should be illegal. These results may assist in guiding ongoing debates over appropriate stalking legislation and strategies to reduce the incidence of stalking, as well as indicating whether education regarding stalking laws is required.

Awareness, prior use, and intent to use emergency contraception among Montana women at the time of pregnancy testing.

OBJECTIVES: To identify factors associated with awareness of emergency contraception (EC), prior use of EC, and intent to use EC in the future among women at the time of pregnancy testing. METHODS: A convenience sample of women presenting for pregnancy testing and being found to be pregnant in 38 primary health care facilities completed a self-administered, anonymous questionnaire. Information regarding demography, pregnancy intentions, use of any contraception, awareness of EC, prior use of EC, and intent to use EC in the future was collected. RESULTS: Of the 583 women that completed the questionnaire, 62% were aware of EC, 4% had previously used EC, and 13% considered using EC in the future. Women aware of EC were more likely to be white, have > or = 12 years of education, and report use of birth control prior to the current pregnancy. Younger women, those with < 12 years of education, and those not currently living with a partner were more likely to have previously used EC. Women who considered using EC in the future were more likely to be younger, non-white, have < 12 years of education, not currently living with a partner, and their usual source of care was a public clinic. Women who considered using EC in the future were also more likely to not want to be pregnant now or ever (21%) compared to women who wanted to be pregnant now or sooner (12%), or with those who were unsure of their current pregnancy (7%). CONCLUSION: Strategies need to be developed to increase the awareness of EC and determine the factors that would assist in enhancing its utilization.

Predicting future blood donor returns: past behavior, intentions, and observer effects.

A prospective design was used to explore the efficacy of 6 factors (e.g., intentions) to predict the number of future blood donations in an initial sample of 630 blood donors. Differential predictions are made for the roles of past behavior and intentions with respect to occasional (4 or fewer previous blood donations) and regular (5 or more previous blood donations) blood donors. Intentions were predictive for occasional donors, and past behavior was predictive for regular donors. Furthermore, for regular donors only, an inverted U-shaped curve explained the relationship between past behavior and future behavior. Finally, it is reported that observing others fainting produces a reduction in the number of future donations for occasional donors. The theoretical and practical implications of these findings are discussed.

The mediating role of self-efficacy in the development of entrepreneurial intentions.

The purpose of this study was to investigate the mediating role of self-efficacy in the development of students' intentions to become entrepreneurs. The authors used structural equation modeling with a sample of 265 master of business administration students across 5 universities to test their hypotheses. The results showed that the effects of perceived learning from entrepreneurship-related courses, previous entrepreneurial experience, and risk propensity on entrepreneurial intentions were fully mediated by entrepreneurial self-efficacy. Contrary to expectations, gender was not mediated by self-efficacy but had a direct effect such that women reported lower entrepreneurial career intentions. The authors discuss practical implications and directions for future research.

Evidence that implementation intentions reduce dietary fat intake: a randomized trial.

This study evaluates the effectiveness of an intervention based on the concept of implementation intentions for reducing dietary fat intake. Participants (n=264) completed questionnaires on their motivation to eat a low-fat diet before being randomized to either an experimental condition, which required them to form an implementation intention, or a control condition. Results showed that, after 1 month, fat intake, saturated fat intake, and the proportion of energy derived from fat decreased significantly in the experimental group but not in the control group. This difference could not be explained by differences in motivation between the 2 groups. The findings are discussed in relation to the use of implementation intentions instead of tailored interventions to change behavior in general populations.

Intentional forgetting can increase, not decrease, residual influences of to-be-forgotten information.

Intentionally forgotten information remains in memory at essentially full strength, as measured by recognition and priming, but access to that information is impaired, as measured by recall. Given that pattern, it seemed plausible that intentionally forgotten information might have a greater impact on certain subsequent judgments than would intentionally remembered information. In 2 experiments, participants cued to forget nonfamous names were subsequently more likely to make false attributions of fame to those names than were participants instructed to remember them. These findings implicate retrieval inhibition as a potent factor in the interplay of recollection and priming in memory and judgment. They also point to possible unintended consequences of instructions to forget, suppress, or disregard in legal or social settings.

Predicting the intentions of women in domestic violence shelters to return to partners: does forgiveness play a role?

Recent findings indicate that college women's forgiveness of hypothetical dating violence was predictive of their hypothetical decisions to stay in the relationship. This study was designed to evaluate the role of forgiveness in women's intentions to return to their partners from a domestic violence shelter. A sample of 121 women residing in both urban and rural domestic violence shelters filled out a series of questionnaires evaluating demographic information, severity of violence, attributions for violence, psychological constraints (or investment), and forgiveness of the partner. Forgiveness was found to predict intention to return to partner over and above the other variables studied. These findings suggest that the degree to which women are willing to "move on" from the abuse and to let go of their anger toward their partners may play a significant role in their intention to remain in a relationship with their partners.

Intentional forgetting as a facilitator for recalling new product attributes.

When market changes alter what product attributes are deemed important, consumers may intentionally try to forget old product information in an attempt to remember new product information. In Experiment 1, the authors demonstrated that intentional forgetting of this nature temporarily inhibits retrieval of old product information and leads to a benefit to memory for new product information. The results show that, after a short delay, benefits continue in the absence of costs, which is supportive of a multiple-process account of intentional forgetting. Experiment 2 extends these effects using an advertising message to stimulate forgetting. Across both experiments, results also show that brand preference is based on learning of new attribute information.

Forgetting of intentions in demanding situations is rapid.

Demanding work settings often require the deferral of intended actions. In 3 experiments, participants were to withhold a response until they encountered a task change (which occurred 5, 15, or 40 sec later). To approximate highly demanding settings, the experimenters sometimes divided attention during the delay period. During some of the delays the experimenters interrupted the participants with an additional task (Experiment 1). Demanding conditions as well as interruptions revealed rapid forgetting of intentions at levels that would be considered significant in applied settings. Experiments 2 and 3 showed that this rapid forgetting was not reduced by strategic rehearsal and implementation intention strategies. The results suggest that maintaining intentions over brief delays is not a trivial task for the human cognitive system.

Clinician validation of Poison Control Center (PCC) intentional exposure cases involving prescription opioids.

Poison Control Center (PCC) cases involving intentional ingestion, injection or inhalation of prescription opioids are a potentially valuable source of information on the abuse and misuse of these products. This study sought to validate PCC classifications of prescription opioid intentional exposure cases against clinical diagnostic criteria. 4,321 cases were reviewed. PCC-clinician concordance was good to excellent for Withdrawal, Abuse, and Suicide (kappa statistics: 0.73, 0.53, 0.48, respectively), but poor for Misuse and Intentional Unknown (Specific motive not known). Interrater reliability among clinicians was good (weighted kappa range: 0.56-0.68). Results demonstrate the degree of compatibility between PCC and standard nosologic classifications.

The effect of right cerebral hemisphere damage on collaborative planning in conversation: an analysis of intentional structure.

This study investigated the impact of right cerebral hemisphere damage on the capacity to take shared responsibility for the development of an intentional structure in conversation. Intentions are important determiners of both discourse structure and utterance meaning in context. Right-hemisphere damaged (RHD) individuals have been reported to have difficulty in the use of prosody as well as performing and appreciating the process of discourse tailoring which is dependent on recognizing speakers intentions. Audio taped samples of naturalistic conversations between RHD individuals and normal speakers were analysed. Text-level discourse processing analyses involved measures of global discourse structure and self-monitoring accuracy. Prosodic analyses included fundamental frequency (F0) resetting, pause durations and inter-turn intervals. The results revealed that speakers with right cerebral hemisphere damage do not, first, use prosody to alert listeners to changes in discourse structure, and, second, assume equal responsibility for the development and maintenance discourse structure.

Differences in the types of musical regularity learnt in incidental- and intentional-learning conditions.

Several studies have found learning of biconditional grammars only under intentional rule-search conditions (e.g., Johnstone & Shanks, 2001). Memorization of strings merely led to the learning of chunks. We used a musical grammar, a diatonic inversion, that is a type of biconditional grammar. Participants either were required to memorize a set of grammatical tunes (incidental learning), or were asked to search for the underlying rule whilst being given feedback about their performance (intentional learning). The results showed that participants in the incidental-learning condition did not learn the inversion rule and merely acquired explicit knowledge about chunks. However, participants in the intentional-learning condition learnt both the inversion rule and chunks.

Understanding behavioral intention to participate in virtual communities.

Virtual communities are formed on the Internet and are expected to serve the needs of members for communication, information, and entertainment. Online businesses should consider virtual communities as a new market place since their members are current or future customers. Thus, there is a need to understand the determinants of member intentions to participate in virtual communities. Based on the extended theory of planned behavior (TPB), this study develop a research model to identify the attitudinal, social, and perceived behavioral control factors that would influence members intentions to participate in virtual communities. Specifically, the research model decomposes the attitude component into perceived usefulness, perceived ease of use and perceived trust, and the perceived behavioral control component into Internet self-efficacy and facilitating conditions. Based on a survey of 165 community members, this study uses structural equation modeling (SEM) approach to investigate the research model. The results indicate that attitude and perceived behavioral control significantly influence member behavioral intentions, while subjective norms do not. Finally, this study discusses the implications of these findings and offer directions for future research.

Intention to breastfeed and other important health-related behaviour and beliefs during pregnancy.

BACKGROUND: It is widely accepted that breastfeeding is the best form of infant feeding for the first 4-6 months of life. OBJECTIVE: This study explored whether intention to breastfeed is associated with other positive maternal health-related behaviours and beliefs during pregnancy. METHOD: A cross-sectional survey was carried out with 789 women attending antenatal clinics at Leicester Royal Infirmary NHS Trust. A structured questionnaire assessed feeding intention, use of folic acid, vitamin and iron supplementation, smoking status, smoking stage of change, and fetal health locus of control during pregnancy. RESULTS: Forty percent of the women stated that they intended to breastfeed exclusively, 27% planned to bottle feed, 23% intended to combine breast and bottle feeding and 10% were undecided. Women planning to breastfeed (either exclusively or in combination with bottle feeding) were more likely than those with alternative feeding plans to: have increased their folic acid intake, taken vitamin/iron supplements and have a primarily internal locus of control (perceive themselves to have control over the health of their unborn baby). Women intending to breastfeed were also less likely to smoke. Of the women who did smoke, those planning to breastfeed were more likely to be either considering or preparing to quit smoking during their pregnancy. CONCLUSION: In addition to educating pregnant smokers about the risks of maternal smoking, primary health care practitioners could also usefully address their knowledge, health beliefs and feeding intentions during antenatal care.

Determinants of older adults' intentions to vaccinate against influenza: a theoretical application.

BACKGROUND: Despite many government initiatives, uptake of the trivalent influenza vaccine among the older adult population still remains suboptimal. If immunization rates are to be optimized, new approaches for identifying the determinants that facilitate or inhibit influenza vaccination decision making in this population are necessary. METHODS: An extension of the theory of planned behaviour (TPB) provided the theoretical framework for the development of a multi-item questionnaire. One hundred and ninety-three white, independent living and city dwelling men (n =77) and women (n = 116), completed the measure. The main outcomes of interest were future vaccination intentions. RESULTS: Overall, the TPB predicted 48.2% of older adults' intentions to vaccinate next influenza season. Receiving the vaccine in the past and anticipating feelings of regret (the impact of missing a vaccination opportunity) contributed to increments of 10.7 and 13.7%, respectively, in explaining this intentional behaviour. CONCLUSION: Utility of theoretical frameworks is a useful resource tool for understanding the rationale behind the facilitating and inhibitory determinants of older adults' vaccination decision-making processes. The implications of this research are discussed with a view towards future directions for maximizing influenza vaccination uptake initiatives using theoretically driven applications.

Predicting registered nurse job satisfaction and intent to leave.

BACKGROUND: Nurse job dissatisfaction has been the primary predictor of intent to leave; however, although many predictors of job satisfaction have been identified, little is known about the influence of variable nurse attitudes, such as psychological empowerment and hardiness, on job satisfaction. OBJECTIVE: The purpose of this study was to investigate the relative influence of nurse attitudes, context of care, and structure of care on job satisfaction and intent to leave. METHODS: A nonexperimental, predictive design evaluated these relationships in a nonrandom sample of 90 registered staff nurses using instruments with known psychometric properties. RESULTS: The major predictor of intent to leave was job dissatisfaction, and the major predictor of job satisfaction was psychological empowerment. Predictors of psychological empowerment were hardiness, transformational leadership style, nurse/physician collaboration, and group cohesion. CONCLUSIONS: Results supported the influence of nurse attitude on job satisfaction relative to other contributing factors.
