Is implicit learning perceptually inflexible? New evidence using a simple cued reaction-time task

Considerable research has been devoted to investigating learning without awareness. Burke and Roodenrys [Burke, D., & Roodenrys, S. (2000). Implicit learning in a simple cued reaction-time task. Learning and Motivation 31, 364–380] developed a simple learning task in which a cue shape predicts the arrival of a target shape (to which subjects respond) in a sequence of rapidly presented shapes, and found that all subjects responded faster to cued targets than to uncued targets, even those classified as unaware of the cue–target relationship. Two experiments were conducted to examine the perceptual flexibility of implicit (and explicit) learning using the paradigm developed by Burke and Roodenrys (2000). Perceptual flexibility was examined by altering the perceptual features of the cue shape. The results of the first experiment indicated the implicit, but not explicit, learning that occurs in this paradigm is perceptually inflexible. However, the second experiment indicated that perceptually flexible implicit learning can be encouraged by varying the nature of the experimental stimuli. These experiments therefore provide support for processing accounts of transfer.     

Stress appraisals influence athletic performance and psychophysiological response during 16.1 km cycling time trials

ObjectivesWe examined how stress appraisals were associated with emotions, coping behaviours, as well as subjective and objective measures of performance.DesignProspective field- and laboratory-based studies.MethodsIn Study 1, 192 athletes completed process-oriented psychometrics pertaining to the aforementioned constructs throughout a sporting competition. Study 2 utilised an experimental design to assess the causal influence of stress appraisals on performance, cortisol, and psychological variables. Thirty gender-matched athletes were randomly assigned to either a stress appraisal (e.g., challenge, threat, benefit, or harm/loss) or the control group. Participants completed three 16.1 km cycling time trials (TT) on a cycle ergometer, with their appropriate stress appraisal engendered via falsified performance feedback throughout the final TT. Salivary cortisol samples and psychometrics (e.g., appraisals, emotions, and coping) were collected before and after each TT.ResultsThe results of Study 1 revealed a sequential link between challenge stress appraisals and perceived goal attainment via pleasant emotions and task-oriented coping behaviours. Threat stress appraisals inversely related to goal attainment via unpleasant emotions and both distraction- and disengagement-oriented coping. In Study 2, no significant psychophysiological or performance differences were found across genders. The temporal orientation of stress appraisals influenced objective cycling TT performance. Benefit and harm/loss stress appraisals significantly facilitated or inhibited performance, respectively. Cortisol spikes were observed in the stress appraisal group’s threat, challenge, and benefit, with a decline detected within the harm/loss group. Whilst the process of winning is physiologically stressful, the fear of defeat may be more stressful than losing itself.ConclusionStress appraisals influence subjective and objective performance, as well as neuroendocrine and psychological responses to stress.     

How does mindfulness modulate daily stress response: evidences from ambulatory assessment

Objective: Mindfulness has been found to be associated with less adverse stress response. However, little is known about how mindfulness modulates stress response in the real daily life. The current study investigated the relation between daily stress and negative emotions, and explored a mediational link via perceived loss of control, and moderation by dispositional mindfulness, to better understand this association. Design: A total of 95 college students were recruited to complete a questionnaire and to report on their stress, perceived loss of control and negative emotions in daily life. Main Outcome Measures: Mindful Attention Awareness Scale (MAAS) was used to assess dispositional mindfulness. Stress, perceived loss of control and negative emotions were assessed by ambulatory assessment. Results: Stress was positively related with negative emotions at within-person level. Perceived loss of control mediated the relationship between stress and negative emotions. Furthermore, participants with higher levels of dispositional mindfulness showed an attenuated association between stress and anger, and also attenuated associations between perceived loss of control, and anger and fatigue at within-person level. Conclusion: These findings point to perceived loss of control as an important key factor in daily stress effects. Dispositional mindfulness appears to have beneficial effects in that it attenuates the impact of daily stressors on individuals’ wellbeing. Clinical implications and limitations are discussed.     

The context counts: Congruent learning and testing environments prevent memory retrieval impairment following stress

Stress before retention testing impairs memory, whereas memory performance is enhanced when the learning context is reinstated at retrieval. In the present study, we examined whether the negative impact of stress before memory retrieval can be attenuated when memory is tested in the same environmental context as that in which learning took place. Subjects learned a 2-D object location task in a room scented with vanilla. Twenty-four hours later, they were exposed to stress or a control condition before memory for the object location task was assessed in a cued-recall test, either in the learning context or in a different context (unfamiliar room without the odor). Stress impaired memory when assessed in the unfamiliar context, but not when assessed in the learning context. These results suggest that the detrimental effects of stress on memory retrieval can be abolished when a distinct learning context is reinstated at test.     

Relationship between driving styles and biological behavior of drivers in negative emotional state

ObjectiveThis paper explores the links between driving style and the biological behavior of people while driving with dangerous negative emotions (such as anger, anxiety, and fear).BackgroundIt is highly important to study the behavior of humans from varying aspects to discover the factors affecting it. Driving style, as one of the critical aspects of the human factor, and biological behavior, as a factor influencing the performance of individuals, motivate us to examine the relationship between the two.MethodFor this purpose, a test was designed to record the biological signal data, namely, the Electrocardiogram (ECG), Electroencephalogram (EEG), Electromyogram (EMG), and Electrodermal activity (EDA), in a driving simulator with driving events prompting negative emotions. The Multidimensional Driving Style Inventory (MDSI) was employed to determine the driving style of participants.ResultsCorrelation analysis was engaged for data analysis. The results showed, firstly, a significant relationship between the participants’ driving style and their biological behavior and, secondly, the highest correlation between the EEG signal and driving style. Moreover, participants with a nervous and anxious style showed maximum change in biological behavior, while those with a reckless style displayed minimum alterations in biological behavior at the time of unpleasant events during driving.ConclusionConduction of such research can help better understand the behavior of different people while facing unpleasant driving events.

The use of the psychological stress evaluator with stutterers

A lie detection instrument, the Psychological Stress Evaluator, has been reported by the manufacturer as being capable of quantifying changes in the degree of “stress” as reflected by a subject's voice. Speech pathologists might consider the use of the instrument in clinical and research activities concerning the stutterer's emotional (stress) reaction to stuttering.To test the validity of the instrument, four stutterers and four normal speakers were recorded while making consecutive telephone calls. Randomized recordings were analyzed by a company trained technical to determine the degree of stress for each speech sample.Results indicated that both groups had a significant reduction of stress from the first to the fourth telephone call. However, the groups did not differ in the degree of stress during the ordered series of calls. Due to the inability of the Psychological Stress Evaluator to differentiate between the groups, the validity of the instruments is questioned.     

Bottom-up and top-down factors of motion direction learning transfer

Perceptual learning of motion discrimination has long been believed to be motion direction specific. However, recent studies using a double-training paradigm, in which the to-be-transferred condition was experienced through practicing an irrelevant task, found that perceptual learning in various visual tasks, including motion direction discrimination, can transfer completely to new conditions. This transfer occurred when the transfer stimulus was subconsciously presented, or when top-down attention was allocated to the transfer stimulus (which was absent). In the current study, observers were exposed subconsciously, or directed top-down attention, to the transfer motion direction, either simultaneously or successively with training. Data showed that motion direction learning transferred to the transfer direction, and suggest that motion direction learning specificity may result from under-activations of untrained visual neurons due to insufficient bottom-up stimulation and/or lack of top-down attention during training. These results shed new light on the neural mechanisms underlying motion perceptual learning and provide a constraint for models of motion perceptual learning.     

Perceived control and emotions: interactive effects on performance in achievement settings

Individual differences in cognitions and emotions play a critical role in difficult academic situations, such as the transition into college, a period infused with uncertainty. Perceived academic control (low vs. high) and emotions (course boredom, anxiety, and enjoyment) were examined to determine how they jointly predicted 620 first-year students’ achievement and attrition over an entire academic year. It was expected that students’ emotions would moderate the effects of high perceived control on achievement (final psychology grade, cumulative GPA) and attrition (overall course credits dropped). Regression results revealed several Perceived Control  ×  Emotion interactions that supported this moderation hypothesis: negative emotions impeded the benefits of high control (i.e., boredom and anxiety predicted worse performance in high-control students); positive emotions enhanced the benefits of high control (i.e., enjoyment predicted better performance in high-control students). Conversely, achievement emotions did not predict performance among low-control students. Together, these findings indicate that for a high level of perceived control to enhance students’ academic achievement and inhibit attrition, “adaptive” levels of emotions (lower boredom, lower anxiety, or higher enjoyment) are required. Implications for maximizing academic success among both low- and high-control students are discussed.

The influence of motivational and emotional factors in mathematical learning in secondary education

IntroductionWhile motivation has, for decades, been investigated as a key component of academic learning and performance, academic emotions have often been left out of the scope of investigation. According to several researchers, mathematics learning seems to be particularly affected by students’ emotions.ObjectiveThis paper is aimed at characterizing the emotions and motivation of eighth grade students in a mathematical setting and highlighting the cluster of emotions–activity emotions vs outcome emotions–which best predict math value, math self-concept, behavioral engagement and math performance.MethodData were collected through questionnaires from 115 students and analyzed through means comparisons and linear regressions.ResultsResults indicated that eighth grade students give a relatively high value to mathematics have a positive mathematics self-concept and are moderately engaged in mathematical tasks. Regression analysis showed that mathematics value and behavioral engagement are better explained by activity emotions while mathematics self-concept and performance are better predicted by outcome emotions.ConclusionThe implications of these findings in terms of educational practices are discussed at the end of this study.     

Lexical information drives perceptual learning of distorted speech: evidence from the comprehension of noise-vocoded sentences

Speech comprehension is resistant to acoustic distortion in the input, reflecting listeners' ability to adjust perceptual processes to match the speech input. For noise-vocoded sentences, a manipulation that removes spectral detail from speech, listeners' reporting improved from near 0% to 70% correct over 30 sentences (Experiment 1). Learning was enhanced if listeners heard distorted sentences while they knew the identity of the undistorted target (Experiments 2 and 3). Learning was absent when listeners were trained with nonword sentences (Experiments 4 and 5), although the meaning of the training sentences did not affect learning (Experiment 5). Perceptual learning of noise-vocoded speech depends on higher level information, consistent with top-down, lexically driven learning. Similar processes may facilitate comprehension of speech in an unfamiliar accent or following cochlear implantation.     

Anxiety and post-traumatic stress symptoms following wisdom tooth removal

The purpose of the present study was to determine the psychological impact of wisdom teeth removal and to identify the psychological risk factors for the development of dental anxiety and post-traumatic stress symptoms. Participants were 34 consecutive elective patients referred for surgical removal of a wisdom tooth under local anesthesia. Frequency of previous distressing dental events and general traumatic life events were assessed at baseline (t1), and emotional distress (pain, state anxiety and disturbance) immediately after treatment (t2). Post-traumatic stress responses were determined three days after treatment (t3), and at four weeks follow-up (t4), while severity of dental trait anxiety was assessed at t1 and at t4. Two patients (8%) met screening criteria for Post-Traumatic Stress Disorder (PTSD) at t4. Multivariate analysis revealed that previous exposure to distressing dental events and pre-operative anxiety level predicted anxiety level at t4, accounting for 71% of the variance. Severity of pain during treatment was a significant predictor variable of PTSD symptom severity at t4 (25% explained variance). The findings underline the importance of pain-free treatments and awareness of patients' individual predisposition to anxiety or trauma-related symptoms to reduce the risk of iatrogenic psychological harm.     

Beyond perception: Testing for implicit conceptual traces in high-load tasks

The present commentary addresses the main results obtained in the Butler and Klein [Butler, B. C., & Klein, R. (2009). Inattentional blindness for ignored words: Comparison of explicit and implicit memory tasks. Consciousness and Cognition, 18, 811–819.] study and discusses them in relation to the Perceptual Load Theory of Lavie [Lavie, N. (1995). Perceptual load as a necessary condition for selective attention. Journal of Experimental Psychology: Human Perception and Performance, 21, 451–68.]. The authors claim that the use of implicit indexes of conceptual distractor processing in high-load situations would be an important addition to the load literature, which would benefit the research field regardless of their positive or negative findings.     

Attentional sets influence perceptual load effects,but not dilution effects

Perceptual load theory [Lavie, N. (1995). Perceptual load as a necessary condition for selective attention. Journal of Experimental Psychology: Human Perception and Performance, 21, 451–468.; Lavie, N., & Tsal, Y. (1994) Perceptual load as a major determinant of the locus of selection in visual attention. Perception & Psychophysics, 56, 183–197.] proposes that interference from distractors can only be avoided in situations of high perceptual load. This theory has been supported by blocked design manipulations separating low load (when the target appears alone) and high load (when the target is embedded among neutral letters). Tsal and Benoni [(2010a). Diluting the burden of load: Perceptual load effects are simply dilution effects. Journal of Experimental Psychology: Human Perception and Performance, 36, 1645–1656.; Benoni, H., & Tsal, Y. (2010). Where have we gone wrong? Perceptual load does not affect selective attention. Vision Research, 50, 1292–1298.] have recently shown that these manipulations confound perceptual load with “dilution” (the mere presence of additional heterogeneous items in high-load situations). Theeuwes, Kramer, and Belopolsky [(2004). Attentional set interacts with perceptual load in visual search. Psychonomic Bulletin & Review, 11, 697–702.] independently questioned load theory by suggesting that attentional sets might also affect distractor interference. When high load and low load were intermixed, and participants could not prepare for the presentation that followed, both the low-load and high-load trials showed distractor interference. This result may also challenge the dilution account, which proposes a stimulus-driven mechanism. In the current study, we presented subjects with both fixed and mixed blocks, including a mix of dilution trials with low-load trials and with high-load trials. We thus separated the effect of dilution from load and tested the influence of attentional sets on each component. The results revealed that whereas perceptual load effects are influenced by attentional sets, the dilution component is not. This strengthens the notion that dilution is a stimulus-driven mechanism, which enables effective selectivity.     

情绪设计对多媒体学习的影响

通过两个实验探讨多媒体学习中情绪设计对学习者情绪、认知过程和学习结果的影响。实验1将内部情绪设计与外部情绪诱发两种方式结合起来,探讨多媒体学习环境中不同方式诱发的积极情绪对学习的影响。实验2进一步聚焦于内部情绪设计,考察颜色和拟人化这两个特定的情绪设计元素对学习者情绪和学习的影响。结果发现:(1)积极的外部情绪诱发和内部情绪设计可以诱发积极情绪,并促进学习迁移。(2)对学习材料进行内部积极情绪设计可以诱发学习者积极情绪,增强学习者的学习动机,降低学习者感知到的学习材料的难度,并促进学习迁移。其中,彩色设计可以诱发学习者积极情绪,但拟人化只有与彩色结合才能诱发学习者积极情绪;在拟人化条件下,彩色设计可以增强学习者学习动机;彩色设计可降低学习者对学习材料感知到的难度;彩色和拟人化都可以促进学习迁移。     

The Brief Stress and Coping Inventory: A Useful Stress Management Instrument

The Brief Stress and Coping Inventory (BSCI) was designed to gather stress and coping information from an individual in 15 minutes, compared to a nearly 1-hour completion time required for the parent instrument. All BSCI scales are described, along with our scoring methodology. Intercorrelations between scales are presented. Reliability and validity estimates were seen to be satisfactory to highly satisfactory. A multiple regression analysis identified 3 out of 8 scales that contributed significantly and uniquely to an optimal predictive equation for illness symptoms (R = .70). Frequency distributions of group results, which greatly help work site managers to understand results from stress management programs, are illustrated.     

Performance and learning goals for emotion regulation

Goal orientation theory is concerned with performance and learning goals in academic, athletic, and other ability areas. Here we examine performance and learning goals for emotion regulation. We define performance goals for emotion regulation as seeking to prove one’s ability to manage emotions; learning goals for emotion regulation are defined as seeking to improve one’s ability to manage emotions. In two studies, we tested the hypothesis that performance goals for emotion regulation would be associated with greater use of defensive emotion regulation strategies and depressive symptoms. Results from both studies showed that individuals with greater performance goals for emotion regulation reported higher levels of rumination and thought suppression and greater depressive symptoms, while individuals with greater learning goals reported greater use of cognitive reappraisal. The findings suggest that goals for emotion regulation may help explain individual differences in use of defensive versus constructive emotion regulation strategies.     

Developing race categories in infancy via Bayesian face recognition

The other-race effect emerges during infancy following the perceptual narrowing of face recognition. Other-race faces that were previously discriminable in early infancy cannot be distinguished by older infants. I discuss a Bayesian model of this process that posits that the other-race effect may be a consequence of learning to distinguish between intrapersonal variation (changes to face appearance that preserve identity) and extrapersonal variation (changes that do not preserve identity) in a visual environment in which a subset of race categories dominate. I demonstrate that race categories, which I have previously argued are a critical precursor to the emergence of the other-race effect in infancy, are a natural by-product of this model. Perceptual narrowing for race may thus be a natural consequence of visual experience and the estimation of face variability based on a growing number of exemplars. I describe the basic architecture of the model, its applicability to a range of visual learning scenarios, and identify critical choices one faces in applying the model to a specific perceptual task. Despite the success of the model in accounting for these behavioural results, I conclude by identifying important shortcomings of the model and describe important challenges for future efforts to characterize the development of the other-race effect computationally.     

A School-Based Approach to Stress Management Education of Students

Stress in children and adolescents has been linked to a variety of physical and emotional problems as well as to poor school performance. Because of these negative effects, school-based special services providers need to implement stress management education programs it optimal learning and development are to occur. Behavioral and cognitive-behavioral coping skills training have been effective in helping students deal with school-related stressors. An approach for stress management education is presented which addresses curriculum content, target trainees, environmental supports, and identification of trainers.     

Emotional dynamics of soccer fans at winning and losing games

The purpose of the present study was to investigate the emotional reactions of fans of winning and losing teams at two professional soccer games. The participants were 187 male and 146 female Japanese soccer fans who provided biographical information and responded to a slightly modified state version of the Tension and Effort Stress Inventory (TESI; Svebak, Ursin, Endresen, Hjelmen, & Apter, 1991) pre-, mid- and post-game. Data from winning and losing fans were analysed using 3 × 2 independent groups ANOVAs for each of the pleasant emotions, unpleasant emotions, and tension stress/effort stress ratings with Bonferroni adjustment to control Type 1 error rates. When winning and losing fans’ responses were compared, most differences were found post-game, where losing fans scored significantly higher than winning fans on boredom, anger, sullenness, humiliation and resentment, and lower on relaxation. Also, levels of pleasant and unpleasant emotions changed significantly for losing fans, but (except for boredom) not for winning fans.
