AFFORDANCES BETWEEN
PERCEPTION AND ACTION
Affordances (Gibson, 1979) action
opportunities that the environment offers
to the subject
Affordances concern BOTH perception
and action, they refer both to the world
and to the individuals, they are variable
Ellis & Tucker (2000): microaffordances: brain assemblies of
visuomotor associations concerning
specific action components – beyond a
purely externalist view (Gibson)
(for a review Thill et al. 2013)

context
!"#$%&temporary'/variable ! based on online
visual information. E.g., current orientation of
an object handle.
No dichotomy but continuum

Task: Is the object in the picture the same as the
object mentioned in the sentence (Zwaan et al,
2002)?
Borghi & Riggio, 2009
LANGUAGE AND
STABLE VS. VARIABLE AFFORDANCES
TRUE ITEMS: RTs were faster
with upright than with reversed objects - i.e.
in case of correspondence between the canonical
affordance location (up, down), and the field in which it
was presented (upper, lower).

LANGUAGE: SIMULATION AND
BEYOND
Language and simulation:
Language recruits perception, action and emotional
systems (re-use) (Anderson, 2010, 2014; Gallese,
2008) affordances
But it also modifies them: e.g. it is more sensitive
to stable and to functional affordances
Beyond simulation: language is also a tool
performing actions in the physical and social space:
words modify our space perception (presence of
others)
Linguistic and social info have a major influence
on how we represent abstract concepts

ABSTRACTION AND ABSTRACTNESS
Capability to abstract: sophisticated human ability
Difference ABSTRACTION – ABSTRACTNESS
Categorization always implies some sort of abstraction: e.g.
dog – animal. Animal more general, but still it may evoke a
collection of single, bounded and concrete referents.
Here focus on abstractness. E.g. freedom, fantastic
vedi metafore; idiomi

Different kind of grounding. More abstract

referents. E.g. “truth” (talk by K. PASTRA)
Complexity. “abstract concepts often capture

and mental
events” (Barsalou, 2003). E.g. “cause”

PROBLEM – EG THEORIES
AND ABSTRACT WORDS
Abstract words = crucial test for embodied theories
Most evidence limited to concrete and highly imageable
words (focus on action words and sentences)
How can we claim that abstract words are grounded in
perception, action, emotion systems?
(see work on abstract emotion terms by Moseley, 2012,
2013; Dreier et al., 2015 talk by PULVERMUELLER)
ABSTRACT CONCEPTS
AND EMBODIED THEORIES
Abstract concepts (e.g. “freedom”, “philosophy”) =
the challenge to explain them has become urgent due
to the widespread of embodied and grounded theories
Important only for embodied theories? NO!
e.g. distributional theories (meaning = co-occurrence
of words in large corpora)
do not have specific problems in explaining abstract
concepts
but they are unable to convincingly explain all kinds
of concepts due to a symbol grounding problem
(talk by ANGELO CANGELOSI)
WAT (Words As social Tools) VIEW
Words are tools, not pointers: Beyond a
referential view of words grounding
Words are social tools which:
help us to interact with the social and physical
environment
modify perception and categorization
extend our cognitive abilities
Beyond a purely embodied view, at the bridge with
an extended view of cognition.

on
Modality of Acquisition (Wauters et al., 2003):
perceptual vs. linguistic word acquisition. With age
increase of linguistic acquisition. E.g. pencil, art, tundra
Great amount of known words. In order to acquire
“hard” words, children need to master a consistent
amount of words and of linguistic knowledge (Gleitman
et al., 2005).
Influence of language. Influence of language more
marked in the conceptualization of words referring to
relations (verbs, prepositions) than to objects or
animated entities (nouns) (Gentner, 2006; Gentner &
Boroditski, 2011)
>N
ABSTRACT CONCEPTS ACQUISITION:
ROLE OF SOCIAL COMPETENCES
Infants: importance of linguistic and social input.
Mothers produce abstract words (e.g. «all gone»;
«more») also in absence of their referent (Bergelson &
Swingley, 2013): importance of the linguistic/social input.
Infants. Social abilities. When children start to fixate
the words said by their parents . Abstract words
comprehension: sophisticated social cognition abilities
are required: 10 months, 14 months: ability to follow
others’ gaze and engage in joint action (Bergelson &
Swingley, 2013)
Children.Testimony. Literature on testimony: 3-4
year olds: able and keen to monitor information sources,
particularly in relation to abstract domains (god, religion,
death, etc.)
>O
ABSTRACT CONCEPTS: BOTH
GROUNDED AND EMBODIED
E.g. fantasy,
ntasy fantastic,
fantastic freedom,
freedom free
;'(&'/<P
;%**1$"P
Grounded. Both concrete AND abstract words
are grounded in experiences.
Embodied. Due to their link with language,
abstract concepts should activate the
mouth-related motor system more, while
concrete concepts activate vedi
the hand-related
metafore; idiomi
motor system more.
Attention! This does not imply that abstract
concepts are not represented also in terms of
their semantic content! (Wilson-Mendenhall et
al., 2013)

ACQUISITION OF NOVEL CATEGORIES
AND ACTIVATION OF THE MOUTH
Training 1. participants either manipulated novel
objects / observed groups of objects interacting in novel
ways. Concrete defined as: manipulable, single object as
referent.
Training 2: they read the linguistic labels referring to
concepts (e.g., “fusapo”) (labels could be accompanied
by an explanation of their meaning).

Categorical recognition task:
Before and after linguistic training.

categories was better than that with
abstract categories.
The linguistic training facilitated
more abstract than concrete

With no linguistic training hand

with linguistic training the

Body part rating: evaluate how much

mental states and of both mouth and

thus it
might seem obvious that signs are grounded in
perception and action.
But with signs referring to abstract concepts, a
mixture of actions and linguistic information is used: –
language complements perception and action
Linguistic information could derive from different
sources:
from the same sign language (e.g., the LIS
IMPOSSIBLEAA sign derives from the LIS sign
POSSIBLEAA),
from a foreign sign language as ASL (e.g.,
LANGUAGE/LINGUA and LINGUISTICS)
from spoken/written Italian (e.g., TRUE).

system
Language is not only a communication system, but a
control system that programs human mind manipulating
sensorimotor experiences (Lupyan & Bergen, 2015).
Language can provide a means of building predictions: for
example, listening to a word can help our visual system to
process noisy inputs (Lupyan & Clark, 2015).

WHICH MECHANISM UNDERLIES THE
ACTIVATION OF THE MOUTH?
Re-enactment? (possibly through inner speech)
We could represent abstract words re-enacting the
linguistic/social experience of their acquisition, including
the sounds of the words, and the explanations of their
meanings
Supporting evidence:
acquisition of novel words: the responses with the
mouth are faster when explanations are provided
the mouth responses are faster after linguistic training
abstract words are associated to the acoustic modality?

WAT AND INTROSPECTIVE VIEW:

Possibility to reconcile WAT and introspective view of
abstract concepts (Barsalou & Wiemer-Hastings, 2005)?
Grounding in situations and introspection. More
social aspects of situations and introspective properties
elicited with ACWs E.g., Barsalou & Wiemer-Hastings (2005).
Role of introspection: due not only to content (e.g.
high presence of mental words) but to an internal
mechanism (e.g. talking to oneself?) – this could
explain the mouth activation.
