Incidental learning of sequential information occurs in visual, auditory and tactile domains. It occurs throughout our lifetime and even in nonhuman species. It is likely to be one of the most important foundations for the development of normal learning. To date, there is no agreement as to how incidental learning occurs. The goal of the present set of experiments is to determine if visual sequential information is learned in terms of abstract rules or stimulus-specific details. Two experiments test the extent to which interaction with the stimuli can influence the information that is encoded by the learner. The results of both experiments support the claim that stimulus and domain specific details directly shape what is learned, through a process of tuning the neuromuscular systems involved in the interaction between the learner and the materials.

Recognition memory was investigated for naturalistic dynamic scenes. Although visual recognition for static objects and scenes has been investigated previously and found to be extremely robust in terms of fidelity and retention, visual recognition for dynamic scenes has received much less attention. In four experiments, participants view a number of clips from novel films and are then tasked to complete a recognition test containing frames from the previously viewed films and difficult foil frames. Recognition performance is good when foils are taken from other parts of the same film (Experiment 1), but degrades greatly when foils are taken from unseen gaps from within the viewed footage (Experiments 3 and 4). Removing all non-target frames had a serious effect on recognition performance (Experiment 2). Across all experiments, presenting the films as a random series of clips seemed to have no effect on recognition performance. Patterns of accuracy and response latency in Experiments 3 and 4 appear to be a result of a serial-search process. It is concluded that visual representations of dynamic scenes may be stored as units of events, and participant's old
ew judgments of individual frames were better characterized by a cued-recall paradigm than traditional recognition judgments.

Categories are often defined by rules regarding their features. These rules may be intensely complex yet, despite the complexity of these rules, we are often able to learn them with sufficient practice. A possible explanation for how we arrive at consistent category judgments despite these difficulties would be that we may define these complex categories such as chairs, tables, or stairs by understanding the simpler rules defined by potential interactions with these objects. This concept, called grounding, allows for the learning and transfer of complex categorization rules if said rules are capable of being expressed in a more simple fashion by virtue of meaningful physical interactions. The present experiment tested this hypothesis by having participants engage in either a Rule Based (RB) or Information Integration (II) categorization task with instructions to engage with the stimuli in either a non-interactive or interactive fashion. If participants were capable of grounding the categories, which were defined in the II task with a complex visual rule, to a simpler interactive rule, then participants with interactive instructions should outperform participants with non-interactive instructions. Results indicated that physical interaction with stimuli had a marginally beneficial effect on category learning, but this effect seemed most prevalent in participants were engaged in an II task.

Although it has recently been demonstrated that source monitoring (SM) processes may mediate the relationship between working memory (WM) and false memories, little research has investigated whether the quality of monitoring processes can account for this reduction. In the current study, participants performed multiple false memory, WM, and SM tasks. Consistent with previous research, SM abilities mediated the relationship between WM and false memories (regardless of whether or not participants were warned of the illusions at encoding). High SM individuals were better able to recall contextual information from study to correctly reject lures, whereas low SM individuals were more likely to rely on the quality of retrieved details to reject lures. These results suggest that individuals low and high in SM abilities rely on qualitatively different monitoring processes to reduce errors, and that individual differences in diagnostic monitoring strategies may account for previous relationships found between WM and false memories.

This study investigates whether children who are Dual Language Learners (DLLs) and who have poor reading comprehension will benefit from participating in the EMBRACE intervention. The reading comprehension program is based on the Theory of Embodied Cognition, which focuses on the embodied nature of language comprehension. Our understanding of language is based on mental representations that we create through experiences and are integrated with according sensorimotor information. Therefore, by engaging the motor and language system through reading stories on an iPad that prompt the children to manipulate images on-screen, we might improve children's reading strategies and comprehension scores. Fifty-six children participated in reading three stories and answering related questions over a period of two weeks. Results showed that the intervention was successful in increasing reading comprehension scores in the physical manipulation condition but not in the imaginary manipulation condition. Although lower motor skill scores positively correlated with lower comprehension skills, the children's motor deficits did not moderate their performance on the intervention.

Working memory is the cognitive system responsible for storing and maintaining information in short-term memory and retrieving cues from long-term memory. Working memory capacity (WMC) is needed for goal maintenance and to ignore task-irrelevant stimuli (Engle & Kane, 2003). Emotions are one type of task-irrelevant stimuli that could distract an individual from a task (Smallwood, Fitzgerald, Miles, & Phillips, 2009). There are studies that show there is a relation between emotions and working memory capacity. The direction of this relationship, though, is unclear (Kensinger, 2009). In this study, emotions served as a distractor and task performance was examined for differences in the effect of emotion depending on participants' working memory capacity. The participants watched a mood induction video, then were told to complete a complex-span working memory task. The mood induction was successful- participants watching the negative emotional video were in a less positive mood after watching the video than the participants that watched a neutral video. However, the results of the complex-span working memory task showed no significant difference in the results between participants in the negative versus neutral mood. These results may provide support to an alternative hypothesis: cognitive tasks can diminish the effects of emotions (Dillen, Heslenfeld, & Koole, 2009).

In this study, the oppositional processes theory was proposed to suggest that reliance on semantic and episodic memory systems hinder originality during idea generation for divergent thinking tasks that are generally used to assess creative potential. In order to investigate the proposed oppositional processes theory, three experiments that manipulated the memory accessibility in participants during the alternative uses tasks were conducted. Experiment 1 directly instructed participants to either generate usages based on memory or not from memory; Experiment 2 provided participants with object cues that were either very common or very rare in daily life (i.e., bottle vs. canteen); Experiment 3 replicated the same manipulation from Experiment 2 with much longer generation time (10 minutes in Experiment 2 vs. 30 minutes in Experiment 3). The oppositional processes theory predicted that participants who had less access to direct and unaltered usages (i.e., told to not use memory, were given rare cues, or were outputting items later in the generation period) during the task would be more creative. Results generally supported the predictions in Experiments 1 and 2 where participants from conditions which limited their access to memory generated more novel usages that were considered more creative by independent coders. Such effects were less prominent in Experiment 3 with extended generation time but the trends remained the same.

It has been suggested that directed forgetting (DF) in the item-method paradigm results from selective rehearsal of R items and passive decay of F items. However, recent evidence suggested that the passive decay explanation is insufficient. The current experiments examined two theories of DF that assume an active forgetting process: (1) attentional inhibition and (2) tagging and selective search (TSS). Across three experiments, the central tenets of these theories were evaluated. Experiment 1 included encoding manipulations in an attempt to distinguish between these competing theories, but the results were inconclusive. Experiments 2 and 3 examined the theories separately. The results from Experiment 2 supported a representation suppression account of attentional inhibition, while the evidence from Experiment 3 suggested that TSS was not a viable mechanism for DF. Overall, the results provide additional evidence that forgetting is due to an active process, and suggest this process may act to suppress the representations of F items.

Prospective memory is defined as remembering to carry out specified actions in the future. Research has suggested that prospective memory retrieval is reliant on multiple cognitive processes to function, and the ways in which these different processes are used is dependent on a variety of variables relating to the prospective memory task at hand. The current study focuses on the strength of the association between the prospective
memory cue and the prospective memory intention. Based on literature suggesting that aspects of prospective memory are reliant on executive control functioning, the current study examined the possibility that executive control depletion would affect prospective memory ability on subsequent tasks. Results showed that depletion of executive control resources, measured objectively, did not impair prospective memory in either a low or
high cue-association condition. However, participants‟ subjective assessment of their own fatigue correlated significantly with their subsequent prospective memory performance, regardless of association condition. The results of the study indicate that depletion studies that fail to account for both objective and subjective measures suffer from an unclear interpretation of effects, and that recognition of perceived expectancies
of cognitive resource limitation can assist in improving prospective memory ability.

This study was conducted in order to create a brief task that more efficiently studies the memory of young and old dogs compared to previous dog radial arm mazes. The hypotheses were older dogs would perform worse than younger dogs, brief tasks with longer delays and the presence of an occluder would produce worse results, and the brief task with the longest delay period without an occluder would be most correlated to the radial arm maze. 45 dogs were tested from a previous sample that had participated in a radial arm maze experiment. The dogs were tested in their owner's homes and watched the researcher place a treat behind one of two boxes. Dogs then waited during different delay periods, of 15, 30, or 45 seconds, and with or without an occluder, which was a curtain. Then, the dog was released to see if it could still remember which box the treat was behind. The results supported all the hypotheses, except the 45-second brief task with an occluder was most correlated the radial arm maze. Additionally, the dogs that had to be excluded from the radial arm maze still had a similar range of results on the brief tasks as dogs that were able to complete the radial arm maze. These results confirm the radial arm maze is very difficult and strenuous on dogs, but the brief task is correlated and probably much more effective at studying memory without these issues. This study can help researchers perfect this simple task in order to study many dogs much quicker and collect more information on dogs' memory. Future studies could overcome limitations including dogs that were not motivated by treats or that were too old to stand up. Specific breeds could be tested or longitudinal studies could be conducted to find differences in memory over time. In the future, this can hopefully relate to human cognitive decline knowledge, as dogs show similar cognitive decline to humans, and help find treatments for cognitive diseases.
