This work is an initial step toward developing a cognitive theory of cyber deception. While widely studied, the psychology of deception has largely focused on physical cues of deception. Given that present-day communication among humans is largely electronic, we focus on the cyber domain where physical cues are unavailable and for which there is less psychological research. To improve cyber defense, researchers have used signaling theory to extended algorithms developed for the optimal allocation of limited defense resources by using deceptive signals to trick the human mind. However, the algorithms are designed to protect against adversaries that make perfectly rational decisions. In behavioral experiments using an abstract cybersecurity game (i.e., Insider Attack Game), we examined human decision-making when paired against the defense algorithm. We developed an instance-based learning (IBL) model of an attacker using the Adaptive Control of Thought-Rational (ACT-R) cognitive architecture to investigate how humans make decisions under deception in cyber-attack scenarios. Our results show that the defense algorithm is more effective at reducing the probability of attack and protecting assets when using deceptive signaling, compared to no signaling, but is less effective than predicted against a perfectly rational adversary. Also, the IBL model replicates human attack decisions accurately. The IBL model shows how human decisions arise from experience, and how memory retrieval dynamics can give rise to cognitive biases, such as confirmation bias. The implications of these findings are discussed in the perspective of informing theories of deception and designing more effective signaling schemes that consider human bounded rationality. 相似文献

One cue that may facilitate children's word learning is iconicity, or the correspondence between a word's form and meaning. Some have even proposed that iconicity in the early lexicon may serve to help children learn how to learn words, supporting the acquisition of even noniconic, or arbitrary, word–referent associations. However, this proposal remains untested. Here, we investigate the iconicity of caregivers’ speech to young children during a naturalistic free-play session with novel stimuli and ask whether the iconicity of caregivers’ speech facilitates children's learning of the noniconic novel names of those stimuli. Thirty-four 1.5-2-year-olds (19 girls; half monolingual English learners and half bilingual English-Spanish learners) participated in a naturalistic free-play task with their caregivers followed by a test of word-referent retention. We found that caregivers’ use of iconicity, particularly in utterances in which they named the novel stimuli, was associated with the likelihood that children learned that novel name. This result held even when controlling for other factors associated with word learning, such as the concreteness and frequency of words in caregiver speech. Together, the results demonstrate that iconicity not only can serve to help children identify the referent of novel words (as in previous research) but can also support their ability to retain even noniconic word-referent mappings. 相似文献

This study explored the process Hispanic immigrant families undergo when immigrating to the United States through the implementation of a constructivist grounded theory methodology. The theory illustrates the process in three phases: Arriving to a new country, Integrating new values, and Maintaining values. Through these phases the constant interaction between cultures and its influence in family dynamics is illustrated. More specifically, this theory suggests immigrant families are open to include elements of the new culture encountered while keeping elements of their native culture present once their basic necessities are met. The sample of the study consisted of 16 parents. These parents incorporated the English language, granted greater freedom to their children, became more involved with the school system, included American traditions in their celebrations, and altered their discipline methods based on their interaction with the new culture. Additionally, parents maintained the value of respect, the Spanish language, fostered family cohesion, and instilled their spiritual beliefs to their children. 相似文献

Decision making often takes place in social environments where other actors influence individuals' decisions. The present article examines how advice affects individual learning. Five social learning models combining advice and individual learning-four based on reinforcement learning and one on Bayesian learning-and one individual learning model are tested against each other. In two experiments, some participants received good or bad advice prior to a repeated multioption choice task. Receivers of advice adhered to the advice, so that good advice improved performance. The social learning models described the observed learning processes better than the individual learning model. Of the models tested, the best social learning model assumes that outcomes from recommended options are more positively evaluated than outcomes from nonrecommended options. This model correctly predicted that receivers first adhere to advice, then explore other options, and finally return to the recommended option. The model also predicted accurately that good advice has a stronger impact on learning than bad advice. One-time advice can have a long-lasting influence on learning by changing the subjective evaluation of outcomes of recommended options. 相似文献

Different European nation-states use the most diverse statistical constructions of foreign origin or ethnic minority populations. Several countries traditionally even shun from producing such data. This makes international comparison a very difficult endeavour. Anyone wanting to perform comparative research on immigrants or (immigrant origin) ethnic minorities in Europe is unavoidably confronted with the most diverse types of national statistical data and has to opt for ad hoc solutions. Attempts at international comparison can thus be very tricky due to data characteristics. It is important that researchers are aware of these problems and do not simply accept data (especially in comparisons) at face value. In this article we embark on a comparative explorative study of the way in which immigrant background and immigration related ethnicity is taken stock of by national statistical institutes in a set of European nation-states. 相似文献

Adolescents with ADHD demonstrate notoriously poor treatment utilization. Barriers to access have been partially addressed through tailored therapy content and therapist delivery style; yet, additional challenges to engaging this population remain. To leverage modern technology in support of this aim, the current study investigates parent-teen therapy for ADHD delivered over a videoconferencing format. In this preliminary feasibility study, teens and parents (N = 20) received an empirically supported dyadic therapy that incorporates skills-based modules with motivational interviewing. The videoconferencing interface was deemed feasible with nearly all families completing treatment. Acceptable therapeutic alliance was reported and key mechanisms of change were engaged (i.e., adolescent motivation to meet goals, parent strategy implementation). Families reported high satisfaction, despite minor disturbances associated with delivering therapy via videoconferencing. Treatment integrity and fidelity were acceptable, though slightly reduced compared to clinic-based trials of the same protocol. Therapists perceived that videoconferencing enhanced treatment for 50% of families. Reductions in participant ADHD symptoms and organization, time management, and planning problems from baseline to post-treatment were noted by parents and teachers. However, open trial results of this study should be interpreted with caution due to their uncontrolled and preliminary nature. 相似文献

This study analysed the influence of social debate (group discussion) on previously held antagonistic social representations about tobacco. In the first phase of our study, we contacted 130 subjects in order to know what type of social representations they held. Two representations were found: a ‘psychopathological’ representation and a ‘critical’ one. After obtaining these results, and in a second phase, we randomly divided 100 subjects into 10 discussion groups, whilst another 30 subjects were assigned to the control condition (non-discussion group). The group discussion (social debate) led to a convergence of previously held representations. Debate emerged as a mechanism which could reduce the distance between groups who hold previously opposing representations. 相似文献

This study investigated whether infants' “depressed” behavior (i.e., less positive affect and lower activity levels) noted during their interactions with their depressed mothers generalized to their interactions with their nondepressed nursery teachers. Field et al. (1988) reported that infants of depressed mothers also show “depressed behavior” when interacting with nondepressed female adults, suggesting that the infants develop a generalized “depressed mood style” of interaction. However, in that study the adults were also strangers to the infants, confounding the results. In the present study, eighteen 3-month-old infants interacted with their depressed mothers and also with their nondepressed familiar teachers in 3-minute episodes. The infants' behavior ratings improved when they interacted with their familiar teachers compared to their interactions with their mothers. The infants' low activity levels and negative affect were specific to their interactions with their depressed mothers. Thus, the data suggest that the infants respond differentially to depressed and nondepressed adults who are familiar. 相似文献
