We are what we eat: How food is represented in our mind/brain

Despite the essential role of food in our lives, we have little understanding of the way our knowledge about food is organized in the brain. At birth, human infants exhibit very few food preferences, and do not yet know much about what is edible and what is not. A multisensory learning development will eventually turn young infants into omnivore adults, for whom deciding what to eat becomes an effortful task. Recognizing food constitutes an essential step in this decisional process. In this paper we examine how concepts about food are represented in the human brain. More specifically, we first analyze how brain-damaged patients recognize natural and manufactured food, and then examine these patterns in the light of the sensory-functional hypothesis and the domain-specific hypothesis. Secondly, we discuss how concepts of food are represented depending on whether we embrace the embodied view or the disembodied view. We conclude that research on food recognition and on the organization of knowledge about food must also take into account some aspects specific to food category, the relevance of which has not been sufficiently recognized and investigated to date.     

Spontaneous non‐verbal counting in toddlers

A wealth of studies have investigated numerical abilities in infants and in children aged 3 or above, but research on pre‐counting toddlers is sparse. Here we devised a novel version of an imitation task that was previously used to assess spontaneous focusing on numerosity (i.e. the predisposition to grasp numerical properties of the environment) to assess whether pre‐counters would spontaneously deploy sequential (item‐by‐item) enumeration and whether this ability would rely on the object tracking system (OTS) or on the approximate number system (ANS). Two‐and‐a‐half‐year‐olds watched the experimenter performing one‐by‐one insertion of ‘food tokens’ into an opaque animal puppet and then were asked to imitate the puppet‐feeding behavior. The number of tokens varied between 1 and 6 and each numerosity was presented many times to obtain a distribution of responses during imitation. Many children demonstrated attention to the numerosity of the food tokens despite the lack of any explicit cueing to the number dimension. Most notably, the response distributions centered on the target numerosities and showed the classic variability signature that is attributed to the ANS. These results are consistent with previous studies on sequential enumeration in non‐human primates and suggest that pre‐counting children are capable of sequentially updating the numerosity of non‐visible sets through additive operations and hold it in memory for reproducing the observed behavior.     

Building therapeutic relationship in schizophrenic and alcohol-related disorder cases

Current literature on the dual diagnosis in cases of schizophrenia and alcohol dependence has reported how pharmacological treatment has positive effects on the reduction of both disorders. Nevertheless, patients have considerable difficulties in following the prescribed medication. This work aims to build an engagement stage and therapeutic relationship in seven patients with schizophrenic and alcohol-related disorder cases. This result was achieved through the use of the vignette technique and narrative psychodynamic approach during group counselling sessions. Positive and Negative Symptoms Scale (PANSS) and Munich Alcoholism Test (MALT) were applied before and after treatment. A follow-up session was organized. The PANSS and MALT scores indicated there was no reduction of the psychiatric symptoms after treatment. The follow-up session showed positive outcomes in terms of increasing the level of socialisation as well as awareness of their own condition; at the same, an adherence to pharmacological treatment and psychotherapy for all the subjects.     

Truth in Fiction,Impossible Worlds,and Belief Revision

We present a theory of truth in fiction that improves on Lewis's [1978] ‘Analysis 2’ in two ways. First, we expand Lewis's possible worlds apparatus by adding non-normal or impossible worlds. Second, we model truth in fiction as (make-believed) belief revision via ideas from dynamic epistemic logic. We explain the major objections raised against Lewis's original view and show that our theory overcomes them.

Longitudinal associations between mindfulness and well-being in people with multiple sclerosis

Background/Objective: Depression, anxiety, fatigue, and sleep problems are typical conditions reported in people with multiple sclerosis (MS), often resulting in a reduction of their quality of life (QOL) and well-being. Mindfulness is a multifaceted and complex construct that has been increasingly explored for its correlated to well-being. Despite preliminary evidence, longitudinal data about the impact of mindfulness on QOL in MS remain limited. In addition, Langerian mindfulness, one of the prominent approaches to mindfulness, is yet unexplored in this field. The study aims to examine the longitudinal relationships between two forms of mindfulness (Langerian and contemplative) and QOL, anxiety, depression, fatigue, and sleep. Method: Within a larger randomized controlled trial of an online mindfulness-based stress reduction intervention, a cohort of 156 people with MS was recruited and assessed for both mindfulness constructs, QOL, anxiety, depression, fatigue, and sleep problems. Assessments were repeated after 2 and after another 6 months. Results: Both mindfulness constructs were highly correlated with all investigated outcomes. Both Langerian and contemplative mindfulness predicted higher QOL, lower anxiety, depression, fatigue, and sleep, over time. Conclusions: In both approaches dispositional mindfulness is a protective factor against depression, anxiety, fatigue, and sleep in people with MS.     

Whose hand is this? Differential responses of right and left extrastriate body areas to visual images of self and others’ hands

The extrastriate body area (EBA) is involved in perception of human bodies and nonfacial body parts, but its role in representing body identity is not clear. Here, we used on-line high-frequency repetitive transcranial magnetic stimulation (rTMS) to test the role of EBA in self–other distinction. In Experiments 1 and 2 we compared rTMS of right EBA with stimulation of left ventral premotor cortex (vPM), whereas in Experiment 3 we compared stimulation of right and left EBA. RTMS was applied during a hand laterality task in which self or others’ hand images were presented in first- versus third-person view (Experiments 1 and 3), or while participants had to explicitly recognize their own hands (Experiment 2) presented in first- versus third-person view. Experiment 1 showed that right EBA stimulation selectively speeded judgments on others’ hands, whereas no effect of left vPM stimulation was found. Experiment 2 did not reveal any effect of rTMS. Experiment 3 confirmed faster responses on others’ hands while stimulating right EBA and also showed an advantage when judging self with respect to others’ hands during stimulation of left EBA. These results would demonstrate that EBA responds to morphological features of human body contributing to identity processing.     

Executive dysfunction affects word list recall performance: Evidence from amyotrophic lateral sclerosis and other neurodegenerative diseases

The Rey Auditory Verbal Learning Test (RAVLT) is widely used in clinical practice to evaluate verbal episodic memory. While there is evidence that RAVLT performance can be influenced by executive dysfunction, the way executive disorders affect the serial position curve (SPC) has not been yet explored. To this aim, we analysed immediate and delayed recall performances of 13 non‐demented amyotrophic lateral sclerosis (ALS) patients with a specific mild executive dysfunction (ALSci) and compared their performances to those of 48 healthy controls (HC) and 13 cognitively normal patients with ALS. Moreover, to control for the impact of a severe dysexecutive syndrome and a genuine episodic memory deficit on the SPC, we enrolled 15 patients with a diagnosis of behavioural variant of frontotemporal dementia (bvFTD) and 18 patients with probable Alzheimer's disease (AD). Results documented that, compared to cognitively normal subjects, ALSci patients had a selective mid‐list impairment for immediate recall scores. The bvFTD group obtained low performances with a selectively increased forgetting rate for terminal items, whereas the AD group showed a disproportionately large memory loss on the primary and middle part of the SPC for immediate recall scores and were severely impaired in the delayed recall trial. These results suggested that subtle executive dysfunctions might influence the recall of mid‐list items, possibly reflecting deficiency in control strategies at retrieval of word lists, whereas severer dysexecutive syndrome might also affect the recall of terminal items possibly due to attention deficit or retroactive interference.
