What is Temporal Extension
A motivational object
Today Tomorrow A week foward And so on…
The perceived psychological distance between the present moment and a determined motivational object located in the past
or the future.

Sample
• 353 participants
• Mostly (77.8%) Psychology College students(Faculty of Psychology and Educational Sciences, University of Coimbra, Portugal)
• 290 (82.2%) are female and 63 (17.8%) are male
• Ages between 17 and 61 years old (M = 20.21; SD = 5.30).
Temporal Extension Inventory of Coimbra – TEIC
• The inventory consists of 14 items (two of which are control), designed in Guttman scale of 7 points, which are composed of statements located in the psychological past or future
• The response options The response options are: 2 months, 6 months, 1 year, 3 years, 5 years, 10 years and 20 years or more
• Includes two dimensions related with how far in the future (Future Temporal Extension) or in the past (Past Temporal Extension) the individuals' motivational objects are located
Temporal Extension Inventory of Coimbra – TEIC
• All TEIC items were developed without any affective valence, in order to avoid possible biases concerning positive or negative events existing in the individuals' psychological past or/and future
• Items examples (translated from the original Portuguese items):• «I have the habit of thinking how my life is going to be in the next…»• «Regarding my profession, I know where I want to be in the next…»• «I still have present in my mind people with whom I spent some time
in the last…»• «It´s usual for me to make plans or projects for the next…»

TEIC Gender Differences
• In the Past Temporal Extension significant differences were found (p < .05), male participants presented the highest values (MMale = 18.99 vs. MFemale = 16.85)
• In the Future Temporal Extension, no significant differences were found (p = .22), still the female participants presented the most highest values in this temporal dimension (MFemale = 22.24 vs. MMale = 21.11).
TEIC Exploratory Factor Analysis
The EFA revealed three unique factors:
• Past Temporal Extension (explained variance = 30.77%, 6 items, α = .83)
• Future Temporal Extension (explained variance = 14.99%, 4 items, α = .70)
• Future Work Temporal Extension (explained variance = 9.93%, 2 items, α = .41)
The total model explains 55.69% of the total variance.

Final Thoughts
• Regarding the EFA, the model revealed three unique factors
• The items factor loadings are very high, ranging from .59 to .86 in its respective factor
• None of items load simultaneously in two or more factor above the .30 value
• The items communalities are also very high, showing values between .41 and .71
Final Thoughts
• Regarding the CFA, the model presented an acceptable fit in several indices
• As expected, the two main components (Future and Past Extensions) were moderately correlated.
• We believe that the cognitive processes of thinking too far away either for the future or the past can be related.
Final Thoughts
• The evidence collected allows us to suggest the TEIC as a valid measure for investigators studying Temporal Extension and its overall impact on motivation and behaviour
• Still, the addition of a few more items could be an possible solution to address some psychometrical problems with the Future Labor subscale
• When designing this instrument, one of our main goals was to develop a measure which was easy to use, score and interpret.
